Poor quality
Ordered for a Sig 1911, When I received the barrel and measured everything out, I noticed that it definitely requires barrel fitting in the upper and lower Lugs, Ok. (Problem 1) Went on to inspect the barrel rifling and they were worse than my factory Sig 1911 barrel (striations about the grooves); however, chamber and headspace was much tighter with the Ed Brown. Barrel bushing fit the barrel extremely well, but bushing OD=.697 and it fit loosely in the Sig Slide. Barrel hood dropped in and barrel locked up in the slide no problem, with the exception the chamber was not concentric to my firing pin hole,Ok, need to fit upper lugs. Hood width measured .421 and while difficult to precisely measure length of hood to first locking groove, Im assuming it to be around 1.213. Pushing the barrel forward in the slide with the provided bushing installed, I noticed quite a bit of light on the rear and sides of the hood, however lockup was better than my factory Sig Barrel and should aid in reliability with my Sig over a Match fit barrel overall. When attempting to check the barrel timing, I needed to remove the link in order to start making annotations where the upper lugs need work. (Problem 2) I noticed the barrel link was swaged into place, I attempted to remove and couldnt With a 32 oz ball hammer on a gunsmith block using a carbide punch, only thing I was doing was mushrooming the pin even more. If consistency is found in this area the link pin will need to be drilled out and replaced in order to fit lower locking lugs without towing in the lower lugs, which measured .360 in width. After problem 1 and 2, Ive submitted a return request, however, I may live with the barrel rifling the way it is and lap it in with some 185 grain SWC @ 1050FPS loads 300 times going in 100 round increments and clean with some JB, then see how the bore looks. I will also need to drill and replace the pin myself so that I may keep the barrel for a defensive/plinking purpose barrel. Bushing ID (Thin Flange)=.581 Bushing OD=.697 Barrel Muzzle OD=.580 Lower lug width=.360 Barrel hood to first locking lug =1.213 Lower locking needs fitting so the slide goes into battery, be careful not to remove too much on upper lugs so you have a good lockup on the lowers otherwise you may shorten your dwell time, I wouldnt worry too much on concentricity of firing pin hole with this drop in, as long as it will safely ignite a small pistol primer. If your asking for perfection I suggest a match fit barrel, opening of the slide stop link pin hole is probably going to have to happen on my Sig 1911 due to how much has to be removed from the rear of the lower locking lugs, so Id suggest a .212-.216 chucking reamer in .001 increments and a counter sink for chamfering the hole. All in All the barrel is ok, and would recommend these when they are on sale, and should be installed by a competent gunsmith. If I can provide an update once barrel install is complete and accuracy testing can be provided, I will so. Thank you Brownells for all that you provide and support our 2A!
NICE BARREL NOT A DROP IN BARREL
This is a nice barrel, but I own a Model 70 Government Colt. It takes a lot of work to fit this barrel. Not sure where the drop in part of this barrel is. I guess it is better than a raw barrel
1st barrel swap
This is my 1st barrel swap. Bushing is a nice fit, wasn't a complete drop in. almost thought the link might be to long but did some research and was able to fit the lower lug. No movement at all at full battery. Very happy with the fit and look, haven't taken it to the range yet
