1911’s in general, 9mm versions specifically

All this talk about Tisas got me interested, just bought this oneView attachment 917614

Two fistfuls of .38 Super and Jesus Malverde...

The A1 models have poor sights that can’t be easily changed, no front strap checkering, and no beavertail grip safety. All are things you want, and the sights and beavertail are functionally requirements. The Stingray has a bob tailed grip (which I hate). If you don’t want a threaded version, don’t the B9- they are available lots of places.

Stingray it is!

I purchased one of the Tisas B9BA stingrays. It’s their aluminum framed commander length, with the bobbed grip. Then I fortunately, found this thread as a good tinkering reference.

Anyone have any useful maintenance tips for 1911 aluminum frames?

I’ve had a couple aluminum framed pistols, but never anything I held on to for long, and never one in a 1911 platform. It’s a little hard to find reliable info on how best to maintain them because there seems to be a lot bias against them. I’ve read SOME of the older aluminum frame 1911s from the 60s allegedly cracked or galled with use, so now of course all modern aluminum framed 1911s are guilty by association in some people’s eyes. Which logically doesn’t add up, considering beretta, CZ, and etc also use aluminum frames for some models. However, I will concede I’ve seen a lot of galvanic reactions between dissimilar metals in the plumbing on houses. I know enough that dissimilar metals (like aluminum and steel) in contact with one another when exposed to moisture/salts (ie sweat in a holster) or excessive movement (slide reciprocation) does warrant special attention.

Any 1911 guys have some useful insight into this, especially on optimum greasing and/or lubrication?

EDIT: This thread has me on the watch lists for one of the base model b9r steel/government 9mms too. That sounds like a lot of fun paired with some Dawsons. Great topic.

Galling can be an issue if the machining is really rough, but in most cases it's entirely preventable with good lubrication, as you suggest, and shouldn't be a problem with decently made guns. Especially if the gun has a good hard anodizing, you should be fine. I also wouldn't worry about galvanic corrosion. Only exception to that would be a graphite-based lubricant, which could be a problem in damp places or sweaty EDC, as graphite is known to enhance galvanic corrosion. So stay away from anything with graphite in it, and stay away from light oils. Go with a heavy oil, or even better a good lightweight grease, like TW-25b or one of the cherrybalmz greases. Not a heavy grease though, they aren't good in semi-autos. A heavier oil or light grease.

You should be good to go with the frame in general, I wouldn't worry about cracking an aluminum frame these days, esp in 9mm. If it's something you're really concerned about, get a Sprinco Recoil Managment Guide Rod - they absorb a lot of the shock of the slide-on-frame impact with a heavy secondary recoil spring built into the rear of the rod, that gets engaged just before the slide hits the frame. Unlike the ShokBuffs, the Sprinco system actually captures that energy and uses it to propel the slide forward again, so it's win-win. I put one in a .40 S&W Sig 229 about 15 years ago, and it's been the softest shooting .40 I've ever fired. Feels closer to hotter 9mm than .40. I'd love to put one in my 9mm DWX Compact, but they don't make them yet.

Why do you hate bobtail grips? I haven't had one, but have considered getting one (the 4.25" TRP).

Anyone picked up or been able to check out some of the Tisas models?

I picked up a Tisas B9R DS earlier this year, and have been happy with it for the money ($600 from a local sporting goods store).

Had a few malfunctions in the first 200 rounds, but replaced the extractor with a wilson BP extractor and got some staccato 2011 mags and haven't had any issues for the 600 rounds since then.

I've shot it side by side with tisas B9R single stack, and the grip is definitely wider on the dual stack.

Should anyone decide to upgrade the iron sights on a B9R DS, the front sight dovetail is a Novak cut 1911 sight, and the rear sight dovetail is a Glock cut.

I’m the owner of the B9R and shot along with @24valve. I agree with what he said, the DS is a bit wider grip but both shoot well. It also is about the same weight as my single stack B9R because the DS has a polymer frame vs the steel of the B9R. I liked both equally well and honestly think I’d be happy with either gun. My B9R in factory configuration and with factory mags has ran about 400 rounds without a single malfunction, about 200 of which were cheap steel cased American Eagle ammo and the rest were just standard FMJ’s.

I picked up a B9r DS earlier this spring, haven't shot much or at all this summer but its 245rds (all blazer) and no malfunctions. Completely stock at this point. I don't have anything like it to compare but I really like shooting it.
