I’m rebuilding a HS Model 107 Military Citation and had ordered the Service Pak Type II (SKU 69192)from Wolf.. When I went to change the recoil spring I found the enclosed spring in the Service Pak Type II was shorter than the original and also of a larger diameter so it would not fit into the recoil spring hole in the pistol slide. Luckily I had also ordered a Conventional Recoil Spring (SKU 24235) at the same time – that fit nicely - so I was able to continue re-assembling the pistol. If any one else has ordered the same pak you might want to double check the Recoil Spring size in the HS Service Pak Type II to determine if any more are the wrong size. I sent an e-mail to Wolf describing the problem and suggesting they check their stock.
