Yes, but as Single Stack said "clean it once in a while".
The main thing that a lot of folks seem to forget is that using ANY third party parts in a Glock pretty much invalidates the "Lifetime Warranty". Unfortunately, when things do go wrong with third party parts, they usually are catastrophic and one just can't put the stock parts back in a pretend the problem happen with factory parts. The same thing goes for shooting ANY reloads (jacketed, copper washed or cast lead) in ANY Glock, it voids the warranty. I have had at least a half dozen Glocks that had the LaserLyte Recoil Spring device go south and have played h&LL getting things apart and putting them back in operating condition, at a cost, of course. One person sent theirs back to Glock because the didn't like/believe my response and got the "so sorry" letter. Not sure what happened with them since I refused to touch it after he told me I was full of $#!t and that Glock would cover it under warranty.
I don't disagree that some after market/third party part give us an alternative for certain solutions not available with stock parts, but the idea that just swapping a stock barrel with a third party barrel under the premise that you are suddenly going to shoot better is BS.
I have a KKM .357Sig BBL for my G35. I shoot factory ammo as I just don't do much reloading any more.
Just for the record, as I stated in a previous post on a similar situation, I had a k-boom on my G35 with factory Federal 135gr Hyra-Shocks from the early 1990's. Total head separation, blew the mag out of the gun as well as forcibly disassembled the extractor. Didn't break anything, found all the parts, put them back together and runs great ever since.
