Before you start crying about your G44 not working right. It is NOT quite as immune from abuse as previous models. Glock spent several years developing it, as evidenced by the late "44" model number. I remember Gunny teasing us about it a couple years ago in a video. It's taken a lot of testing and tweaking, but they FINALLY got it marketable, but NOT as indestructible as earlier ones. One of the introductory videos mentioned a "rounds between failures" threshhold they achieved with 230 different brands of .22LR. But to keep it fnctioning, we've got to follow the instructions. My G 44 was unique among the new Glocks I have gotten. It had a full printed Users' Manual and a WIRE BRUSH included in the case. http://id.glock.com/assets/feed-posts/full-21673-294732-DG44plusBrushnManual.jpg Glock's website has several downloadable documents including a specific BOOK of instructions for the G44 (You can find it here, if you threw away everything that came in the original case https://us.glock.com/en/downloadable-materials P 26 of the G44 Users/s manual says: Your GLOCK pistol should be cleaned and lubricated as follows: 1. when brand new, before first time it is fired, plus 2. after each time it is fired, plus 3. as required. This will be determined by your pistol's exposure to adverse conditions during storage or use such as rain, snow, perspiration, salt water, dirt, dust, lint, etc. Additionally, your pistol should be cleaned and inspected if it has been dropped or if any broken parts are suspected or malfunctions experienced, plus 4. at least every 100 rounds fired ensuring protection against your firearm jamming or losing accuracy.
