I recently purchased a new Colt 1991 NRM and after 150 rounds I have this. The guide rod has displaced metal on the frame. Is this normal?

i'd be more concerned about the gap in front of the plunger tube! i've never seen anything like that before. were you shooting factory or hot reloads from uncle ned or a gunshow? Umm, I believe you're looking at the slot where the lug of the slidestop goes. I don't see any unusual gap. |

There is nothing wrong, be careful about getting a panic started. Colt does the cut this way. I repeat, that "gap" is not a problem. OP, I think what you are seeing is the normal finish wear that you will get with a painted frame where the guide rod sits. If it does indeed have some peening going on, check the length of the guide rod (is it stock?) and check the spring. I guess it is possible that the gun may of come undersprung for the loads you are shooting. Are you shooting factory loads? I think Colt uses 16 lb factory springs, may try a 18 lb spring, which is what most semi custom builders recommend, and what I run shooting 230 gr loads. The 185 gr target loads shoot good with the 16 lb or 18 lb spring. |
| The gun is brand new and has 100 rounds of WWB and 50 rounds of Winchester RA45T through it. There is definitely an indention where the guide rod has impacted the frame, but it's hard to get a good picture of. I've not noticed this on any of the 1911's I have owned in the past. In fact, I have a used 1991 ORM that does not have this indention. |

Are you talking about the area highlighted below? Looks like there was excess metal left there, and the recoil spring guide is just moving it out of the way.. It shouldn't be a problem, unless there is a ridiculously light recoil spring in the gun. http://i241.photobucket.com/albums/ff35/kemays/highlight.jpg The area right above where you highlighted is actually indented from the guide rod. |

I wouldn't worry about it. It will get to certain point and then stop. |

so it's only on colts that there is the gap. i guess i need to disassemble my uncle's PH bringback! I wouldn't say that only Colt's have it. And, some Colt's have it, some don't. My Combat Elite has it. It is just where the manufacturer cut the frame rail for the slide stop intead of milling a square hole. Some people with the hole have reported that area cracking over time, the fix and recommendation for that is to just cut out that portion of frame rail. It doesn't affect anything. |
