Anyone use and aftermarket barrel in their g19 and g21's and how reliable are they for a full-time carry gun? What barrel makers would you recommend for aftermarket barrels? The G21 I may change over to a 45 Super for hunting season. So the full chamber support would be a plus.


Thanks

I've got lone wolf in 2 of my 3 19's thousands of rounds never an issue.

I have tried S3F on a 21 and Zev on the 19. They are good to go in my book.

Most times problems arise with aftermarket barrels when the user is shooting reloads.  This especially holds true with LWD they tend to machine their barrels with tighter chambers.

If I was buying aftermarket barrel I would buy KKM or Storm Lake.  Just to replace the stock barrel I would not but if I needed a threaded then yeah I would go aftermarket.  The Glock barrel is damn good and just as good as any aftermarket replacement.

The stock barrels are good if they're in the caliber you desire... I have swapped barrels in a few Glocks to KKM not for the potential accuracy increases but for opening up the world of cast loads.
I barely even use cast anymore as many polymer coated and plated bullets are almost as cheap (and lead my bores a lot less).

I wouldn't be opposed to swapping to KKM for a .45super conversion, just make sure you spring it right.

I have had 2 LWD barrels, one took a little longer to work reliably with a can.
But it calmed down after 50 rounds.

I thank each and everyone of you for your feedback on the barrels and their reliability!

My duty gun has an S3F in it, as does every other Glock I carry aside from my 43.

Absolutely no problems trusting them.  

Ran KKM when I owned M&P's and they were great as well.

I just got a 21 lone wolf barrel the old style.  So very limited results so far.

Didn't work at all with 185 swc.

Ran 200 rnds of plated 230 rn no problem at all.
