please let us know how yours looks. Mine didn't shoot as well as my walther p22, so your at least good there. Mine also leaded up quick.
I checked my bore a bit closer this morning, not perfect but not as bad as the ones pictured. I just got it yesterday to replace a lousy P22 I picked up last month.
My story: The P22 functioned ok, no complaints there, the trigger was not that great, the accuracy was not very good as far as group sizes, and I could not get the sights "dialed in". It shot very low at all ranges and way left. I had to move the rear sight way over, so much so that it looked very odd being way off center. The elevation I could do nothing with as no one makes a rear sight adjustable for windage and it already has the lowest front on it. I just decided to cut my loses and dump it. It probably had a barrel issue and I could have sent it in but I chose to just get rid of it. Enter the M&P22c.
I just picked up the 22c yesterday, came home and gave it a quick bore wipe and it looked nice and shiny, oiled it and headed out to the range. I shot approx. 650 rds without much issue. From a solid pistol rest the sights were dead on at 25 yds, slightly low at 10-15, so I tweeked them a bit to get a happy medium. Group size was decent for a 3.5" barrel and far better than the P22 I had. In fact, I say it was like night and day. I used the same ammo I shot in the P22. It's not as accurate as my 10" MKII or my 8" mod17 but it's acceptable to me for a fun plinker. I have a rimfire suppressor in jail and this is why I was looking for a small plinker with threaded barrel.
Rem Golden bulk worked fine but had two duds, not the gun's fault. Rotated and refired them and they worked.
CCI mini mags- no issues
Winchester 333 bulk pack- no issues
Federal Match 325 rd bulk, lead bullets, not plated or jacketed. I was leary of running them through a semi auto as I always prefer plated/jacketed but I tried it and they worked great, in fact they shot the best groups. I used up the entire 325 rds but did have some stovepipes after the 600 rd mark.
I cleaned it last night and did a number of "tweeks" to it. The barrel was leaded up but not as bad as I expected. What I did have was a very heavy buildup of lead on the inside of the suppressor adaptor. That stuff needed scraping and came off in big chunks. The barrel seemed to clean up ok and looked shiny but my aging eyes are not the best. After seeing this post last night I decided to check it closer this morning.
I do see some machining marks in the grooves, the lands look far better and only see a few very minor chatter marks. I decided to lap it this morning. Ran some extra fine valve compound through it with a tight patch and jag. Followed that up with some JB's bore paste and then some buffing paste. Darn thing shows a huge improvement. It shot good to start with so I'll see what it does now on my next trip out, hopefully sometime this week. The range is closed today for a hunter ed class.
