Never used or know much about the acc-u-rail system (if I'm spelling it correctly). Is 1911 takedown same as without? Does it help a lot in accuracy and/or reliability? Better on alloy or steel frame guns? Any feedback or opinions appreciated.

I think there are other/ maybe better options for tightening frame to slide with a steel gun. With the alloy/ Lightweight guns it is a great option, many of these older slides are internally lightened and will crack if squeezed. My father has a Colt LW commander that has been acc-u-railed and it is great, no issues so far, tight and smooth. All in all it is a nice system for tightening very loose frame to slide set. Take down is basicly the same as a gun without them, you just have to be careful about placement of the rails and debris under them before re-assembly.

fine on a game gun.

Not so fine on a practical pistol.

Rails can bend, they fall out, the cut weakens the existing rail...and the main reason---slide to frame fit just isn't that important on a "working" gun. For a game gun they are just fine-like comps, optics, slide guides and other such things for that matter!

This would like be for an older alloy from on a Colt Commander.

Just got a set done on a 9mm ppc auto that I am building. I think they are great but I like a DA I had one snap tryin to get em out to fit an ejector. They dont fall out trust me!! Also if you have Mr. Kreiger put em in have him make you an extra set. The slide frame fit will be tight and must be lubed. I use Mili tec on mine with great result. But that being said I also gutted the gun and cycled it by hand with mili in it to get it slickerized. I have seen several guns that CT Brian put em in and they run fine at least the guns that i have shot of his. I think for a lightweight gun I would opt for them without hesitation. Keep in mind this can change the relationship of the slide to your barrel and you may have to re-fit the lower barrel lugs and link aand have the gun re-timed and if you aren't familiar with it take it to a smith who has worked with the system before. I wouldn't hesitate to put them in a business gun but I am a bit picky about maintenance and my guns gunerally see a brush and solvent after every range session. One other thought is finish options you will have to have the work done prior to refinish and any finish that adds thickness in the rail areas can create problems so whoever refinishes the gun will also have to be familiar with the rail system. Best..... and I think I just got carpal tunnel!!

Well, since my old Colt seems to have a lot of horizontal play, I'm going to give this a try

I have a carry gun with accurails built by Christiansen. Carried everyday, functions perfectly-clean or dirty.
The rails cannot fall-out unless you disassemble the gun and they cannot be bent in the gun-they are surround by metal. You have the same chance of bending one in the gun as you do of bending a rail...

I had them installed on a Colt that had a lot of free play in the slide/frame fit. If nothing else, it certainly won't ever display that again.
The only thing I wish I had done different is I should have gotten at least one extra set of rails for it.
I had more done to the gun than just rails and now it's one of my finest shooting 1911's. It used to be a really clean series 70 Gold Cup.

It was a bit messed up when I got it back so Bob Rodgers did a marvelous job of getting it running perfectly.

Tim had a set installed on one of his works for me. I was a little leery about it after all the internet thrashings on various forums that I'd read, but I trusted Mr. CT Brian to be up on his game, and it was his suggestion. Now that I have the gun back, I have to say, from all I can tell, ya probably gotta be some kind of idiot to break a rail. I can't figure out how it can be done so long as the user is diligent about assembling the weapon. There's no access to the rails when the gun is completely assembled, and therefore, no way to exert leverage against them that might cause damage. At least, that's my opinion.

Secondly, they change the whole feel of the slide to frame "fit". Even while racking the slide, the gun feels like it's one piece. It's hard to describe--it reminds me of a piano hinge's motion--there's *no* looseness in any direction (and I don't mean Les Baer tight )--the gun feels like some kind of "flexible one-pieced" assembly--a hinge is the closest mechanism I can relate it to.

Makes me look like I've been shooting bullseye all my life, too. (and I shoot bullseye about once every 2-3 years; mebbe 25 rounds of it, til I get bored). As soon as I finish proofing it, it'll be my carry gun. It's not the Acc-u-rails I'm concerned about, either. I'm testing ammo reliability.
