If only

He had taken it out on the range and tested it we'd have an idea on weather it works well.
Also had the magazine loaded in the gun then dropped the slide and continued to handle it even though it LOOKED LIKE it didn't chamber a round he should have cleared it to make sure.

 

Meh, I've wasted more than that on other stuff, so what the heck... I ordered a pair to see if they work.

I have two G44s that work fine with eight different OEM mags, so that should help determine if the mags are worth the coin.

 

They are tempting especially at $15 each. The downside is that they ARE ProMag. I've been debating whether to buy one to try or not.

 

4 that amount of $$ i would just buy 1 or 2 and give them a try.

 

following...

I ordered a couple to try, but I don't know when I can get to the range. I'm curious as to what results anyone has.

 

I saw a video posted by Nelson Precision Manufacturing in Arizona where they are developing an aluminum slide for the Glock 44. Their slide has a cut for a Red Dot Site. The NPM web site says the Glock 44 slide is coming soon and pre-order will be available soon. No indication on price.

#1 - ProMag is crap.

#2 - Everything that matters on the G44 slide is steel. I can't see that an all aluminum slide would have any advantage over that.

Love the ad though. "Are you tired of your G44 plastic slide breaking?" No, but I have been trying. Dang thing just keeps going and going and going and going like the Energizer Bunny. Also, how many "real operators" are running G44's?

 

I have been shooting my Glock 44 regularly and it continues to please. I have no problem with the hybrid metal polymer slide. The only reason I can see for having an aluminum slide is to mount a red dot sight.

I wouldn’t want to try to mount a Red Dot Sight on a factory Glock polymer/metal slide.

There are a lot of people who want their rimfire training pistol set up exactly like their centerfire pistol. I think the NPM will garner sales if they can keep the price reasonable.

 

I went ahead and ordered a magazine to try. We will see if this ProMag actually works or not.


As far as mounting a RDS, I considered a dovetail groove adaptor but don't trust the extra weight added with the polymer slide. We will see if Nelson actually ever releases their aluminum slide or not. From what I read and watching their video, you will have to use high velocity ammo only if you run a RDS.

I really would like to use a RDS on my G44 if possible. I have the Swampfox Kingslayer site on my Kel-Tec PMR30 and CP33 and love them.

 

In the Nelson video they were not using a suppressor. I’m curious if the Glock 44 with NPM slide would function reliably with High Velocity or subsonic ammo and a suppressor. The suppressors generally add back pressure which usually translates to more reliable blowback semi autos. With short barrels of 4.5” or less High Velocity ammo tends to be subsonic in 22 LR.

The Nelson video did illustrate how a difference in ammo could affect reliability. The aluminum Nelson slide looked similar to the performance of Advantage Arms aluminum slide conversion kits with various ammo.

I’m curious if you’ll use the internal slide parts of the Glock 44 with a NPM slide or the NPM slide will be complete with barrel and all internal components.

As am I. When I messaged them on Facebook, they said that the slide will probably run between $185 and $220. I'm guessing that is for the standard slide and also for the one with all the cuts/windows. I forgot to even ask if it will come as a stripped slide or complete. They have yet to say when it will actually be available.

I just sent them a message on Facebook asking if the slide will come stripped or complete. I'll update once I hear from them.

 

Thanks for checking with NPM, I hadn’t looked at their FB page. I don’t plan on adding red dot sights to my pistols but depending on my eye sight it might be in my future.

 

Mags arrived today.. some comparison pics with OEM mag... the follower on the Promag is angled a wee bit lower than the Glock mag, range time will tell if that's a problem.

Loaded wtih 15 rounds

 

I finally got a shipping notification this afternoon for my mags. Hopefully it won't take USPS too long to get them delivered.

 

9x19, those actually look really good. Promag has really upped its game in the last decade. Hope they shoot good, and are reliable. Would really up the excitement for plinking with a g44. For sub 15$ magazines could afford quite a few of them.

 

I received 2 magazines yesterday. I got out this morning to try them. 1st they are very hard to load. 14-15 rounds aren't bad but, the last 3 or 4 are hard. I started with CCI standard which run fine in my 10 round magazines, I had failure to eject, failure to feed and stove pipes. Tried Federal Auto Match about the same thing. It ran the last 10 better. Federal bulk HV HP's still had problem with the first few rounds out of the mag. Loaded with 15 rounds they run much better, not perfect. I did not try them loaded with 15 rounds of CCI standard. That's what I got, someone else may have different results.

 

Thanks for posting your results. If I buy these ProMags I doubt I would load more than fifteen rounds. If you can only get reliable functioning with Mini Mag ammo with the ProMags it kind of hurts using the cheap bulk rimfire ammo.

Hopefully the ProMag magazines wear in and reliability improves with use. The more upward pressure from the top cartridge of the mag adds drag on the under side of the slide which can induce failures. Normally where the closing slide hits the top cartridge on the feed ramp is indicative of insufficient recoil impulse. This type of failure is a common occurrence with my Advantage Arms Glock kits with weaker or inconsistent ammo. The more cartridges in the mag compresses the cartridge stack and spring pressure which is aggravated with higher capacity mags.

Typically with weaker ammo I can down load my AA mags to six or seven rounds (out of a 10 round mag) I can get more reliable function.

If the ProMags won’t reliably feed CCI Mini Mags or CCI Blazer when new these new mags probably won’t ever perform very well with cheap bulk when loaded to full capacity.

 

Mine should arrive tomorrow. I plan on loading them up (18 rounds) and will let them sit loaded for a couple of days before using them. I have done the same with all my Kel-Tec CP33 and PMR/CMR magazines and it helps them.

 

I Wonder

In looking at the pic with the loaded mag the spring is in a bind from what I can see.
If at some point they made a flat spring instead of the coil I wonder if it would feed better. Jus thinking out loud. (with my fingers)

 

I figure ProMag used a coil spring to get the capacity they wanted. The quality of the spring might dictate the service life of the spring. McMaster Carr sell coils springs by wire gauge and number of coils per length. A replacement coil spring might be easier to source than a factory flat coil magazine spring.

My factory Glock 44 magazines have gotten easier to load and are still reliable. For the price the ProMag 44 mag might be worth trying.

 

Mine arrived today. I hand cycled CCI Standard, CCI Mini Mag, CCI AR Tactical, and Federal Champion ammo, all 40 grain bullets. Both loaded with 18 rounds (that is all that will fit)

Mag A - number of misfeeds
CCI Standard - first 3
CCI Mini Mags - 0
CCI AR Tact. - first 1
Fed Champ. - 0

Mag B - number of misfeeds
CCI Standard - first 3
CCI Mini Mags - 0
CCI AR Tact. - 0
Fed Champ. - 0

It will be a few days before I can get to the range. The ProMags are .015" thinner front to back compared to the OEM mags. I left both magazines loaded with 18 rounds of Federal Champion until I can get to the range. I don't know if leaving them loaded for a few days will actually help or not. Doing that did help with my Kel-Tec CP33 and PMR magazines

Final note, a mag loader will help with loading the ProMag magazines. I also wish that they would have used a more traditional oval shaped mag spring. It felt like the springs and followers were slightly binding up when trying to load the last 3 rounds.

 

I finally got to the range this morning. The ProMag magazines worked flawlessly in my G44 with Federal Champion 510 40Gr ammo I did not have a single malfunction. I loaded the two magazines three times for a total of 108 trouble free rounds. It definitely makes it better as a trainer for my G19 since mag capacity matches now.

I'm not going to lie and say that I was not expecting problems since after all they are ProMag magazines. I was pleasantly surprised.

Thanks for the follow up, gonna order a couple.

 

Ditto, I've spent more on a flyer before, my experience with ProMag do make me a bit leery.

 

Amen to that, but it's been 10years or more since I've given them a try. Worlds changed a lot since then. Kicked a couple of pro mag magazines off the dock, wife bought a g 42 mag and it works just fine. Probably worth another try, gotta leave room for growth.

 

I was leery about buying any ProMag magazines too. I'm glad that I took the gamble since the two I got work well. The 25 round ProMag that I bought for my Marlin Model 70 actually works too.

 

Found a new video on youtube testing the 18 round ProMag Glock 44 magazine.

Looks like a good review and worked great for him.
I may pick one up Jus for kicks an giggles. Thanks for posting that:t

 

Bought one

Couldn't resist and ordered one. I'll report back after I get a range trip in with it.
