I have a Springfield 1911 that was a prize at a shooting event about 10 years ago. Not a cataloged item but looks like a National Match frame with a basic model slide. I want to mod the frame for a beavertail and want to know if the slides are interchangeable with Colt 1911s.
I have access to a Colt Commander slide and hammer and want to know it the parts are interchangeable. |

Commander frames have a shorter dust cover and shorter rails. Commander slides also have different lengths.
Due to 1911s being different all around I wouldn't mess with swapping slides and frames. Beavertails are a no brainer. There are two types. Just pick out the beavertail you like and get the jig that corresponds. |

In a commander frame, the recoil spring shelf sits farther back than on a govt sized frame.
Bear has made/makes commanders on govt sized frames, they kind of know what they are doing. Just slaping a commander silde on a govt frame will look like ass and may not function without some other part changes. |

NM prefix serial number does not mean national match DUH! My description was based on a late 90's Springfield catalog. Mine did not match any offering in that catalog but the frame and slide looked like they came off of two different models. Rumor had it Springfield would slap together pistols from parts on the shelf for prize guns. Here's a better description. looks like it might be a Mil-Spec at first glance but appears to predate both the Mil-Spec and the GI models. Differences from current models include; front strap under trigger guard not cut back (as in NOT an A1 frame) slide is marked 1911A1 CAL 45 high cut ejection port NO loaded round indicator 3 dot sights Cartouche is behind Springfield Armory stamp on slide not in front as on current models angled slide serrations sides of hammer not parkerized but shiny silver color no beavertail but has extended standard style tail serrated short trigger Serial number in the NM 112000 range standard short guide rod stainless barrel marked S.A. .45 AUTO curved and serrated back strap |

Sounds like a MilSpec or older GI model.
NM prefix indicates that final fitting and assembly was done in the US. I fit a beaver tail GS on mine in a little over an hour using a Wilson jig ($40) and Wilson beaver tail GS ($80) Very simple and good videos on YouTube. Having the logo in the place it is can be very desirable to some in the MEU-SOC 45 thread. |
