That is interesting info..I have had an issue with my 20 but only because the guy I used to have some work done on it didnt know what he was doing.. I took a to a different gun Smith who fixed it I have not had any issues with it since and probly now have over 1200 rounds through it.

I also have probably 8 or 9 other clocks that I've had 0 issues with that have combined, thousands of rounds through them with no issues..ever..have a Glock 34 I know has 10,000 rounds through it..has never jammed or not fired

Have another friend Cody who worked out east for the feds..his boss wanted to see what a Glock would actually take..he spent an entire summer trying to make it fail..
50,000 rounds later..throwing it against brick walls..driving over it..driving over it in mud..he told me he never did get it to fail..impressive..

The local shops here can't keep the new Springfields in stock..talked to shop again tonight..said they are gone as fast as they come in..plan to demo one this weekend..looking forward to it..I took am interested to see how it feels and shoots..
