With the price of ammunition, I recently wanted to give a Glock .22 caliber conversion a try. I had looked over the Tactical Solutions TSG 22 conversion kit while at the Shot Show last year and for appearances sake, was very impressed. A few weeks ago, after ordering this conversion kit, I took it to the local shooting range to try it out. I used the following loads: -Federal 36 gr HP (The Walmart 550 rd value packs) Followed by the manufacturer recommended: -CCI Mini Mag HV I have (2) magazines for this conversion, the one included and one extra I bought. I loaded 13 rounds of each load into each magazine. Out of the 13 rounds loaded, I was unable to get ANY of them to cycle the slide enough to load a new round. I loaded (4) more mags loaded with 14 rounds each (two being CCI and two being Federal). Again, most were FTF, a few were stove pipes and several were failed extractions. I was really hoping that the conversion would work properly and save me some money with ammo costs, but I was not ready to give up. I detail stripped the entire unit, properly oiled and polished the feed ramp. I took it out shooting this afternoon hoping for the best. Again no luck, the same exact problems. I had to cycle the slide by hand after each shot . It looks to me like the slide is not cycling back far enough after each shot. I am not sure if this is because the recoil sping is too strong. My next idea is to try to trim a few coils off of this spring and see if I get better results. I am really hoping I can troubleshoot through this one and get it to function, otherwise I will be very good at clearing drills.
