Great comp, but fitting may be required - Valkyrie Dynamics Punisher Muzzle Brake

This comp has a simple yet effective design for significantly reducing recoil and muzzle flip in full or commander sized 1911 pistols that are not equipped with threaded barrels. It simply replaces the barrel bushing, so theoretically it could be dropped-in within two minutes if all dimensions work for your pistol. I have a Springfield TRP Carry, which uses a 4.25" barrel. The inside diameter of the bushing perfectly fits my barrel with no play whatsoever - - just a Smooth sliding action. Unfortunately, the outer diameter of the bushing was slightly too large to fit into my slide out of the box without some fitting. This can be a bit challenging, as it must be accomplished without reducing the size of the locking lug which protrudes from the bushing. Fitting this comp wasn't a difficult process per se, but it does require time and patience. I used needle files for the first stage of the fitting. Once I could insert the bushing into the slide with some effort, I used a Dremel tool with rubber polishing point to polish out all tool marks left by the files, leaving a mirror-like surface. This gave me a perfect fit where insertion could be accomplished without effort or friction, yet there was no hint of play or looseness. Every gun will be different, with Government or Mil-spec models generally having more play out of the box, and will therefore will be less likely to require fitting, but more expensive 1911s designed for greater accuracy out of the box will have tighter tolerances, thus necessitating some custom fitting. Also be advised that a number of companies sell this exact same comp design with the same finish options, but some of these brands may be designed for a looser fit than this one. One of these is Ptp Tactical, whose version of this comp drops right into my TRP without fitting. That's much more convenient, but will also have a very slight negative effect on accuracy. Is the difference in accuracy noticeable? Probably not, unless you're a long time owner with a great deal of range time under your belt, so that you feel like the weapon is an extension of your arm and you are a very experienced and accurate shooter. I mention these other brand options so you can decide for yourself whether you'd prefer an easy fit or a more accurate, but time-consuming fit.
