Well I installed a Springfield 9mm conversion kit on my GI 45. The problem is, it wont feed properly. The nose of the bullet is hitting the ramp of the barrel chamber. I know I have to take my pistol to a gunsmith. The slide and lock up seems to fit well, but im no pro to really tell if it does. Im no expert here and have little 1911 vocabulary. But what type of job do I ask for? And, most importantly, how much is this type of job going to run me?

Tough part is that a feed ramp for a 9mm is different than a .45..so trying to make it run..could be very frustrating..also you need a different ejector...

are you going to dedicate it to this frame?? trying to get both a .45 and 9mm to run on the same frame will take a little magic

This will be a dedicated 9mm, sorry I forgot to mention that. I already replaced the ejector as well, with a 9mm.

Do you have the proper .030" gap between the frame ramp and barrel ramp? Is the barrel throated and polished? Is the frame ramp polished?


Sometimes 9mms feed fine off unmodified .45ramps, but if not, the easiest thing to do is get the surfaces polished. If there are still problems, this is normally the frame ramp, must be recontoured a bit as there is significant difference in .45 and 9mm rounds.


What 9mm magazines are you using?

I bought a complete 9mm upper on gunbroker last year. It was a complete top end and also had a Wilson slide stop and 9mm ejector and four magazines. All for $200! I tried the same thing, on a GI model. It was aggravating having half a gun lying around so I got a Caspian frame and had it assembled. Even after assembly and finishing it was still under $500.

Worked for me, could work for you.

The gap does not look right, the frame ramp is forward of the barrel ramp. So I already knew this was going to be a problem even before I tried cycling ammo through the gun. Like I was saying, im a rookie at all this still. How to tell if the barrel is throated or polished?

Also, I am useing the SA 9mm mags, and I have one Colt 9mm mag.

I think I might just try that. Thanks for letting me know.

9mm Fun

I started out trying to shoot a 9mm (wishing to do so , anyways) from my Loaded Parke'd 1911 and then after all the discussion I ended up buying another 1911. I was super lucky since I found an ad for an IMBEL 9mm M973. It was in mint condition and was about $ 400 CDN cheaper than a .45 Loaded Springer.

Now I have both calibers to play with and I did not need or have to modify a wonderfully shooting .45 at all.

By the way, this IMBEL is just fabulous. If you thought the Springfields that IMBEL are made really well, you should see this box stock M973. It's way better than any Springfield I've ever shot. Super well finished internals. I just swapped out the hammer (GI style), round MSH, GI grip safety, and GI safety for some high thumb shooting goodies.

Sorry to hijack this thread, but yes, instead of modifying your .45, just buy another M1911. Who knows if your .45 will shoot as well once you've tweaked it to shoot 9mm's.

Cheers,
Barney
