Sloppy Barrel Bushing Fit in P12-45
Does anyone else have a sloppy barrel busing fit in their P12? Para Ordnance has already replaced the slide in my P12 once but I'm having the same problem again. The bushing appears to be made out of a lightweight alloy. Despite this, the lug on the OD of the bushing causes the channel on the inside of the slide to become battered and eventually the bushing becomes loose enough to get your thumb nail between bushing and the front part of the slide. Has anyone else experienced this problem? It hasn't affected the accuracy or performance of the gun but the sloppy fit is annoying and makes the gun appear poorly made.

Yes, I also had the same problem. The fix I used was a "Kings" officer bushing and spring/guidrod system. I had to machine off the rear of the guide rod area for the bushing to work (about 1/8 inch) and fit the heavier bushing to the barrel. Depending on the barrel slop you may have to have a gunsmith do the work for you. In regards to the guidrod, I removed the rubber buffer that came with it on the guide rod. "Kings Gunworks" is on line. You can also get just the bushing as well. THey are really great parts. try brownells.com to look up the parts too.

Thanks for the reply. Did the King's bushing work despite some minor damage to the channel inside the slide? Did you have to do any work to the bushing to get it to fit the slide?

Bushing woes
The bushing shouldn't do that unless something else is wrong. If the recoil
spring goes into a solid stack-up before the slide hits the impact surface
in the frame, the impact is transferred to the lower part of the bushing
via the spring plug. This will cause the lug and recess battering that
you describe.

Remove the spring and pull the slide fully to the rear. Make a pencil
mark on the dust cover that aligns with the end of the slide. Replace
the spring and plug and pull the slide full back again. If the mark
aligns, you're okay. If the front of the slide is forward of the mark,
your spring is too long. Clip a half-coil at a time until the marks align,
then clip an extra half-coil just to be sure.

Keep us posted,

Regretable I am not sure what you mean by damage. I have not had that problem with mine as long as I follow the instructions that come with the kit. If you go to the kingsgunworks.com sight , they will show you what comes in the kit and can answer your questions. the springs in the p12 are factory I believe is 22lbs and the 24lbs for any heave +P loads. Please note that no two firearms are exactly alike. There is not enough space here to go into the fitting of the bushing or the particulars on the "Kings kit" However you are on the correct track to do the research and procede slowly. Get as much info as possible from a lot of sources. You will soon be able to differ good from bad and what works best for you. Good luck and hope all works for you on the gunsmithing. I have never had to cut springs to make a factory gun work, however i do buy a few from Wolff springs in different lbs to ensure the pistol functions with the load i need to use. Cheers Floyd

I interpreted "battered" to mean damaged. I've seen this happen
several times due to excessive spring length. Generally, the bushing
will crack on the lower radius, just at the junction of the flange and
the main body. It has been known to break slides as well. I have
personal experience with one broken slide from an overlength spring.
Luckily, Colt replaced it at no charge, even though the guy put in an
aftermarket spring without checking for coil bind.

Drop-in is often a contradiction in terms...
