Tisas 1911 rebuild

Pretty sure this is what this pistol started out as:

But I have NO idea what the previous owner of this gun did to it. I can say this much, he didn't have any idea of firearm maintenance! Anyway, it cam into the shop last week, I wound up giving it a basic cleaning and then bought it myself. Today, was detail stripping and smoothing of parts. I stopped and bought a metal bread loaf pan at Walmart along with 2 pints of nail polish remover, it's pure acetone, so it was just what was needed to strip the rattlecan gloss black paint off the poor little beast.

Surprrisingly, after about 30 minutes in the acetone bath, the paint came off easily, revealing a good looking slide, which appears to be some sort of stainless steel because neither Oxphoblue or Black Magic would take on the slide! Then out to the garage workbench to smooth up some internal parts and finish the detail scrubbing on the receiver. Just like the top half, the bottom was totally filthy. Smoothed up the trigger bow and got rid of the rough/sharp edges on the grip safety. After measuring the springs, they are all where they should be, so I will try it with the factory springs, if they aren't good I have a set of Wolff's ready to go. I also took some 400 wet/dry sandpaper and got the surface rust off the barrel hood.

Decide if this is a shooting gun or a BBQ gun.  Just that often sets the tone to get you to "perfect".   From the mixed pedigree of parts, this seems to beg to be a shooter or daily carry, not a dressed up gun.

BUT - What parts you use are really what meets your taste and performance goals.  I really like good checkered wood grips on 1911s.  Some folks like G10 plastic with real aggressive checkering, if you need the extra-firm locked-in feeling grip.  And I like a relief cut for the thumb to reach the mag release easily. (But, my tastes would not run towards any of the 3 sets you show. Just me)

I would use the barrel bushing that fits the slide moderately tightly and the barrel moderately tightly.   The heck with the "appearance" - I would go for 100% reliable performance and good enough accuracy.  If you get 3" groups from rest at 25 yards, be delighted.  It's always better for cleaning if the bushing will come out without a bushing wrench, but if I get great accuracy with a tight fitting bushing, I'll put up with always carrying a wrench in my kit.

good luck, GJ

Thanks Joe, good advice. This will never be a BBQ gun, I went that route on a Super .38 some years ago [WHY did I ever let go of that gun?]. Got wood checkered grips right now that could go on it, the Ivory polymer ones have the Mexican Eagle on them and give good grip in addition to looking good. I will try out the bushings, now that it is clean I don't need a wrench on the factory blue one. Haven't shot the beast yet, wanted it clean first. The trigger was poor, but there was so much filth in there, it could not have been anything else.

Nice work.  Is that cerakote on the frame now?  Nice two-tone vibe.

Bigger fixed sights would make it a great carry and WB Traditional gun! 

good luck, GJ

Thanks Joe. I am trying to find out from Tisas' Importer SDS if the front sight is a wide or narrow tenon so I can do just that and swap out the sights for something easier to see and still be WB legal. I think the frame was a ceracoat of some sort from the factory and thankfully they didn't mess with that. The slide has definitely had some sort of coating on it, as the inside is still blued and a magnet will stick to it, so it isn't stainless. Took it into work today and the guys liked how it had turned out. As far as carry, I have a S&W Scandium Commander that is my regular carry gun.

Gun stainless steel is usually a 41x or 44x series stainless, which IS MAGNETIC.    That slide is very different than the common (acid resistant) non-magnetic stainless, like 304 or 316. THOSE are non-magnetic, soft(er), and not amenable to heat treatment due to greatly different alloy content. 

Nope, your slide is gun-grade stainless, almost certainly.

good luck, GJ

I have given up on trying to use tenon mounts for larger/taller front sights, as have many smiths I know.  Tenons just will not hold a heavy sight securely. Pretty easy to have a smith mill a standard dovetail on the front and mount a sight.  Then the front as well as the rear is drift adjustable.  And MUCH more secure.  Perfectly legal for any Wild Bunch shooting.

good luck, GJ
