@Onpoint- Are you you affiliated with Onpoint Manufacturing on gun broker (https://www.gunbroker.com/item/856824011) who seems to be selling the same product as Blackmountain?

I remember when high caps first hit the ipsc/ uspsa scene, Team Colt shooter Jerry Barnhart had Wilson Combat cut/weld up a frame to take Tanfoglio / Springfield Armory P-9 mags...the next year his colt slide was on top an early tripp frame So what is old is new again...

@ltdmstr isnt the length difference of the recoil spring tunnel between a commander and full size such that if you cut a 5" to 4.25 you wont be able to use a commander length spring?

@Tripod Very nice work. I would love to see pictures of the guide rod plug or the front end of the slide. Did you use a trimmed up commander length bull barrel or a cone or something else? Thanks!

@jcc7x7 Are you saying keep the guide rod full length and use a full size reverse plug? If so, do you have a picture of this setup, I am trying to picture how it would look. THANKS!)

I would like to shorten a goverment model slide down and run it on a short/wide dustcover full size STI. My plan is to hacksaw/then trim up on the mill to 4.5" from the original 5", cut the slide for a reverse plug, shorten the barrel and thread it for a cone comp, on a lathe, and use a commander length guide rod and spring. Is there anything I am missing in my plans or any suggestions from someone who has already done one?

@iflyskyhigh is there any holster brands that you found fit best with brownells slide? Thanks

Roughing reamers are used to "rough out" chambers before finish reaming chamber to final dimensions, they save wear and tear on finish reamers. Some smith's use drills or boring bars in lieu of roughing reamers. Finish reamers cut chambers to final dimensions- a finish reamer may also cut the throat of a chamber or not depending on how it was ground (most do). Throating reamers increase the freebore length of a chamber and can possibly change the angle and length of the transition from freebore to barrel dimensions, typically PTG uses a 1.5 degree angle and manson and clymer use a 2 degree angle

New 126mm Gen 2 mag, factory spring/follow/pad, came new with a new gun. The Mag has repeatedly looked like a Pez dispenser with a stuck follower and loose rounds. Other factory mag does not do this with new gun . Any suggestions?

I handled one today, and am impressed for the money. I do not want to pay the $50 each I found online for extra mags. Do you have a link to the $25 mags? Respectfully,

Gun is a small frame SpringfieldArmory early 90's imported P9, barrel from the new upper measures 13.97 mm so I am confident that the slide is in fact a small frame slide (besides the fact that the gentleman who sold it to me knows a lot more about Tanfo's than me). Pretty sure the slide fitment is unrelated, just production tolerances stacking in the wrong direction, micrometer and pin gauges indicated that slide would not go on frame without removing metal, in retrospect maybe I should have done it on my surface grinder but I didnt feel like it at the time , a little more dykem and stoning and the slide will be a nonissue No yapivi sear jig.... What parts are the general consensus to try and replace to make the problem go away? Hammer, sear, saftey and pins?

Unknown number of rounds, 3 owners including me who competed with it since early 90's . I used in in mid 2000's as an open gun till i replaced it with a STI, virtually no rounds.since.05/06ish... Would a video help diagnosis?

Recently I acquired a 9mm iron sight upper for my old 9x21 open P9 world cup. Tonight I started fitting the new slide as it wasnt even close to fitting on. While playing the filing/stoning/dykem application/ wrestling slide back off and repeat game I noticed my hammer falling without touching the trigger particularly when saftey is disengaged hard! Can the safety "over rotate" if the detents aren't doing there job? Any suggestions as to what to look for before I resort to sending it of to a pistol smith? Any suggetions on smith's if it comes to that?

I am needing to set up some 9mm mags for a small frame 9mm. Back when Dinasours roamed the earth, I used WCPI extensions on my mags but they are way over 140mm. Does anybody have recommendations other than a Taylor freelance extension with grams follower and extended spring? What capacity should I expect? Thanks,
