So Steve, how'd the trip to the range go? I'm thinking of geting a KKM replacement for my G23 if they are match-grade accurate as shown by your 50 feet grouping. I've been so out-of-date with gun gadgets so I was wondering if KKM makes replacement bits for other Glock calibers as well?

I ventured to the range this weekend with a partner who has shot the gun in the past.

His comment was "wow, that is an amazing difference."

The groupings tighten up considerably with the KKM barrel -- to the point where with practice a 100 at 15 yards is not out of the question.

In fact while we were zeroing in the .22 for squirrel patrol we joked that I had a better chance under 25 yards of hitting them with the .40.

In my view the upgrade is well worth it. Your results may vary -- I could in fact just be very lucky.

Yes, KKM (and others) make drop in replacements for other calibers (as well as conversion barrels). Check out glocktalk.com for comments from people with more knowledge than me. There are some that ask you to send the gun in for a gunsmith fitting -- probably even better results.

 

Is it because the KKM has conventional rifling versus the Glock polygonal? I thought the polygonal rifling was supposed to be more accurate. That looks like a huge improvement though.

 

Steve C,

Quick question for you. How's the slide-to-frame play and barrel lock-up before vs. after the KKM barrel replacement, i.e., Looser or tighter ? If there aren't any noticeable play/looseness then I'd venture to say that the aftermarket barrel itself makes all the difference in improved accuracy.

Thanks.

Bill
