This post is to discuss Glock 43 Mags... Initially after buying my 43 if the mags were inserted at just the right angle (down and right) they would hang up on the mag catch and they would have to be forced past. This was obviously a problem if i am to depend on these during a life or death reload. Initially Glock was solving this issue buy sending out new mag catches with the corner shaved off. I recently called Glock to get my replacement mag catch and the rep responded by saying "we are actually sending out "gen 2" mags." These mags are marked with an 01 the originals do not have this 01 designation. (see pics) one other thing to note is the mag springs were about an inch longer in the new 01 mags. not sure if they were just stretched but all three were noticeably longer. I have not run the TTI base pads on the new 01 mags yet. Thus far they have run fine with no issues on the old mags 800 rounds combine. I will report back this weekend on reliability with new mags.
