Fitting an aftermarket barrel

[Dolomite]

I just picked up a new Wilson G17 barrel (couldn't say no to the price) and since my Glock 17 only has 3,000 rounds through it – it's no surprise that the new barrel is not dropping in (on my ancient G21, a new KKM plopped right in as if it was falling into an old, familiar EZ chair).

The measurement on my stock barrel between the hood near the breach and top front lug is 1.212”. The measurement on the new Wilson barrel is 1.217”. Assuming that I only need to remove something in the area of less than .005”, does anyone think I’ll be able to get away with just using a fine 6”x0.5”x0.5” Norton aluminum oxide stone I’ve got laying around? I’m hoping I can just lay it flat and run the barrel hood across it until I can fit it into my slide. Does that sound like a do-able plan?

And just so I’m not losing my mind – can I confirm that this is the “hood” that needs to be fitted:

Also, since this is the first time I'll ever be fiting a barrel to a Glock, I'll be covering everything I touch with black sharpie and test fitting everything about every other pass.

Yes, thats the hood at the rear of the chamber. A file might be better but give it a try.

"...remove something in the area of less than .005”

You probably know it but the way it's written sounds different: You want to fit the Wilson bbl. to the slide so it should wind up having a greater measurment than that of the OEM bbl., new or wih XK rounds thru.

Even if you did not get the bbl. from Wilson's give them a call and find out what clearance they recomend, {between it and the slide} etc. May as well fit it as tight as a Match bbl. at 1st., then shoot it a while before "loosening" it up, etc.

Otherwise sounds like you are on the right track!
