"Is the locking block longer where it runs along the slide rails? I have the older model but I did notice it on one of the newer guns. What did Glock say the bigger block was going to solve?"
That's correct. The newer block is a bit longer where it runs towards the front rails. Somewhere on the internet I once saw a picture of the old and new side by side comparing the 2. Unfortunately, I can't find it right now.
According the the Glock engineer who came over from Austria, the longer block is suppose to take some of the flex out of the frame. According to him, with higher rd counts, the more it's shot the more it flexes. This excessive flex was what he said was causing our problems. Maybe it was, but with IN SP and Topeka having problems out of the box, they must be having some other issue. Or maybe the longer block wasn't a fix. I don't know. During late summer/early fall of 2005 we transitioned all our old Glocks for the new upgraded 22. We didn't have the problem IN SP is reporting with new out of the box guns. In fact, I never heard any reports of the new 22s causing problems during the change over shoots. When we transitioned to our original 22 in 1999-2000 it was a 32 hr course with a minimum of 750 rds fired. 2100 Troops with most shooting the 22 (roughly 1.5 mil rds) and I never heard any problems during that time either. So there must be some difference between the 22s that we got late summer and the ones IN SP got recently.
It's definitely perplexing. Some of the high rd count guns caused us problems while the next one issued would run fine.
