Picked up my Glock 44 last week. Got it home and right to the workbench, detail strip and clean without removing the magic copper grease. Only thing out of the usual for Glock was the barrel was covered with oil. Cleaned and 8 drops of oil per instructions. Then I spent a week following The 44 Thread. A bit apprehensive since I sold a perfectly woking TX-22 for funding. Long story short. 15 types of 22lr. Plan was 50 rounds each. Ended up shooting 700 rounds. Out of this 6 FTF, all had solid strikes and fired when reloaded. 10 stove pipes, 9of these with Thunderbolts and the bang was so soft on those 9 I ran a rod to check the barrel. 4 Failure to lock back, all after 400 rounds so I'll clean and see if it still happens. After 700 rounds in 2 hours I'm very happy with this pistol. It ran through 7 different kinds of Bulk Pack. 36,37,and 38 HP's. All RP's where 40's. Velocity from 1130FPS to 1435Fps. Two Hans,strong hand, weak hand, slow fire, double taps, and mag dumps. I use Glocks in IDPA, Steel Challenge,and of course GSSF. Having a 22 with a Glock trigger for practicing control is what I've wanted. It's dry fire with a small bang and visual results. I hope Glock takes care of the people having problems cause this is a winner. If anyone would like info on the types of ammo I used and my thoughts on how they work in the 44 (Don't use CCI Clean 22) just ask!
