sd9ve, reliable as a glock, love it. Issue is i've put about 600 rounds through it and noticed to night when I was cleaning it the cup at the end of the guide rod that sits against the barrel lugs has warped a little bit. I've found Steel guide rod upgrades for it, but i've never been one for putting aftermarket parts in my guns except for sights. What do you guys thing? It runs fine with no issues, but i'd like to get it fixed to avoid possible future issues. Anyone know where I can get a replacement? Thoughts on it all, thanks in advance.
