| How much slide lightening can be done to a pistol without going into open class? I'd like to do more to my XDm 5.25 and machine my backup to match it. I'm also considering switching to an M&P Pro and would like to lighten the slide on that similar to my XDm 5.25. |

As long as you don't port your barrel, I am not aware of any restrictions on how much your slide weighs in any outlaw 3-gun matches. |
| Not a problem for any match rules I know of, but would make your gun ineligible for USPSA Production division. I like to shoot my M&P9 in both 3-Gun and USPSA matches to leverage the training value to the max, so I have avoided mods like lightened slide, replacement match trigger, mag well etc. to remain Production-legal. |

Is production the most common class in USPSA or is there something else? It wouldn't put me in open would it? I also though you could do trigger mods in production. |

Dustin, even lightened you would still be able to use it in Limited, which would also let you load your magazines up to full capacity. I've been using my 3 gun pistol in Limited (minor) so that I can use my 22 round mags. I lose a few points here and there because of the minor power factor (9mm), but I just try to shoot for As.

Less muzzle flip/rise. I like what the cut on the XDm 5.25 did and I want more. I also want it done on my regular XDs that I use as back ups. Quoted:

Why are you lightening your slide? Less muzzle flip/rise. I like what the cut on the XDm 5.25 did and I want more. I also want it done on my regular XDs that I use as back ups. Do you mean the 5.25 flips less than the standard 4.24" barrel XDM9? Reason I ask is the guns with slide lightening I've used don't flip less because they weigh less. The slide cycles faster making the sights return to where the belong quicker. The reason the Glock 34 and the XDM 5.25 have a lightened slide is so they cycle faster like the G17 and XDM9. They can also use the same recoil springs as a result. |

Out of curiosity: when you guys are getting your Glock slides cut & lightened, are you adjusting your recoil spring weight as well? I ran 13 lb ISMI flat springs in my G34's. 15 lb in my G35's. Bullet: 147gr at 950 fps? (Just guessin') |

But time for reloading was never in my schedule so I bought. Now I'm shooting Freedom Munitions 124's in my STI's. |
