Question: Does this fit a springfield 1911
Document: While I don't wear one of these for duty, I do use it for tactical training classes.Pros:- Fit my 1911 full size with no adjustment necessary.- SERPA release is an excellent passive restraing system.
Excellent product, very well made. Holds my 1911 secure until needed. Very solid. I highly recommend this holster for duty use.
The mid- or high-position mounts available for the SERPA holsters are MUCH better and pretty much a must-get.Otherwise, this is just like any other SERPA holster in that it's simple, rugged, functional, secure, and nice-looking.EXTRA BONUS: I bought this to fit a full-size Smith & Wesson M&P45;, but it also perfectly fits my SD9VE.
BLACKHAWK is known for quality, and also how expensive they are lol. This holster is amazing, def. went in the right direction with serpas, and lead the creative curve. I purchased one for my sig 226, very nice, but the only downside is if your running a tac light, at least for sig, this is not friendly, unless you have a blackhawk light as well, others wont fit on there very specific rig.
I already owned one of these for my Glock, and a friend wanted one for his S&W; Sigma .40. Blackhawk's website didn't list the level 2 duty for the Sigma, but most of the CCW holsters are the same and list the Sigma, too, so my friend called Blackhawk to ask if it was the same. The lady that answered said it was, so we ordered it.It turns out that this holser does NOT fit the Sigma without slight mods.
This is a great locking holster. Glock slides right in and is locked there until I need it.. Fits like a glove!Wish they made one for my Walther.
This is a great holster its light weight and durable. I have been a cop for awhile this is the best holster that I have ever owned.
This holster is awesome! I've always liked the Blackhawk holsters and this one is no exception. It fits on my 2 1/4&#34; duty belt perfectly. It has a sturdy platform that is similar to the Safariland holsters. I love how the Serpas retain the weapon and the easy of draw. I would recommend this holster to any shooter or LEO that wants their weapon secure but easily accessible!
The description says that this works well for the Sig 226 with or without rails. Over the years, I have acquired both, but the older model with rails is my primary duty. It does NOT draw smoothly. It's a minor delay, but in a life or death situation, I can't risk having that in play. I will be returning this for a different, smoother drawing holster.All that said, for the models without rails, this is like butter. Solid, dependable, typical Blackhawk.
Strange bit of inconsistency there on Blackhawk's part.
Answer: yes
