This barrel is a gen 4 - Lone Wolf Arms AlphaWolf M/30 45ACP Barrel

I bought this barrel not doing my usual research and I now know that this is for a gen 4 glock 30 not a gen 3 my brother has a gen 4 and this barrel works great suppressed and unsuppressed the locking lug on this has an extra shelf so the guide rod will petrude from the frame about an inch on gen 3s causing miss feeds so do noy try to interchange the barrels between gens and for anyone wondering if this will fit the sf model the standard glock 30 and the glock 30 sf slides are identical the frames are different so you can interchange the slides on the frames but if you own a 30S this WILL NOT FIT I've been seeing that in a bunch of forums people have asked that question and debated it if you think I'm wrong go on the glock website and compare the width of both slides and you'll find an answer if you want a threaded barrel for a gen 3 the kkm seems to have a similar lug to the stock gen 3 but I haven't bought or tested it the only other option is to get this and have a gunsmith modify the lugs to match the gen 3s
