@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,

I looking for suggestions for a source for a replacement barrel for an old tanfoglio /SAworld cup p9 9x21 open gun. Gun is a long slide, set up for bushing barrel but somebody fit a cone comp that has to be removed to get straight barrel out of slide.... I am looking for suggestions as to sourcing: Barrel Bushing Guide rod Recoil Guide rod Cant remember if tanfoglio bushing guns had a recoil plug(been 2 decades since I ran an eaa silver team) I have a decently equiped shop (mill, lathe surface grinder, 9mm chamber reamer etc.) So if I had to make a few parts like guide rode or turn down OD of barrel etc. based off of suggestions/dimensions/pics I could.... Ultimately, I want to make this back into a iron sight 9mm gun. Gun has what I assume to be a LPA supersight cut- has anybody had any luck with Dawson replacement rears? I still have several slidestop pins but want to go back to a real slide stop any suggestions on best source for this?

Betting that the that Sti's threading tool was sharp as you can visually see the threads being taller at the back of the barrel and noticeably shallower at the front but I still thread mic'd it to see how bad it was (bad). Yes I could buy and fit a new barrel and be done but if a 30 dollar cone and a little lathe time get me back in the game....just looking to see if anyone saw a problem with converting the factory bull barrel to a cone comp (I am more of a rifle Smith, turn around ar and bolt gun barrels from blanks all the time, make chassis stocks etc.)...I will make a threaded go no go mandrel from brass or 12l15 to ensure that the comp threads are ok...really would like to salvage the comp as the French border cuts extend out onto it as well as being tired of it wanting a diet of $100 bills...

It this the barrel threads that are damaged comp appears good but I have not made a tight fitting mandrel to confirm it... do not feel that chasing them (barrel threads)on a lathe would help as the pitch diameter has been reduced too much by multiple loosening with ccontinue shootin...272 is what I previously used but if I get it back together I will probably use the black grade for permanent installs of sleeves in engine blocks or rock sett like I have used on suppressor mounts and muzzle breaks on rifle barrels...

Trying to post a picture, not so smart with smartphone.... If you think it would work after you see it, I'm (game as soon as I get some funds, planning stage currently) This slide was originally a long slide bushing gun that had a briley barrel with a custom cone comp (.536x36tpi not the usual .540 X 40 tip that I have read that SA did) I am wanting to change it from an open gun to a 3gun pistol for tactical optics class... and am interested in what the tanfoglio brain trust recommends for a replacement barrel- I have a complete machine shop (mill, lathes, cnc mill, surface grinder...) and this is a slow time for me so cheap with machine/labor is preferred. ..

Bought a 9mm sti open gun on BE back in 06. It was built on sti short block by previous shooter less than 10k rounds allegedly...seller stated that the barrel had the comp come loose before...bought it had tons of fun for one season won a couple plaques with it... comp came loose again so I lock tightened it with high strength...came loose again and I wasn't happy with the thread engagement (from either inspection) so I talked to a Smith who claimed to have a jeweler who could fusion weld it so off it went...came back with a bigger bill than expected but I was willing to pay for no more drama...fast forward a few practice sessions and it was loose again.Out of desperation had the welder I use to weld 700 bolt handles (even though barrel was Ss and comp carbon) TIG it, no love there either. There is no apparent baffle strikes but the barrel threads are under 50% engagement when measured with thread mic, barrel still shoots good and comp still works. I am thinking about breaking it out and seeing if I could salvage the barrel /comp. Does anyone see a problem with turning down the barrel, fitting egw cone comp, and either black lock tighting it or using rocksett...All work would be done one one of the lathes in my shop.... Any problems with this plan? Any suggestions?

Anyone know what lpa sight fits the old P9 world cup slides? Thanks,

Fairly new to glocks, many years of competition and reloading. Picked up a 24 of the classifieds, started out ok for the first 1000rds or so started having jams and a lot of them in the last few weeks. Noticing the cover plate fall half of the gun and prevent it from going into battery, i am also getting 20 percent light primer strikes. Ammo runs fine in my 22. Even tried swapping striker, spring bearing thingy and cover plate from 22, still happens, any suggestions?

I'll second the recomendation for getting a 3 gun model by ready tactical through cwpsa. I recently purchased this model for a gun not listed and had it delivered faster than I thought possible for a custom holster, well under the promised delivery.

Dave was one of the most enjoyable shooters I had the pleasure of ROing at an area match, class act all the way.

George - Benchresters (which I am not) claim Both the lack of boattail and a function of lenght that makes a flat base bullet group better up close but the SHORTER lenght is a much larger contributing factor EricW- Jimmy Knoxx of JLK bullets in Arkansas is a great contact to talk to about the fluid dynamics involved in bullet stabilization, for everyone else who is not an engineer/physicist I recommend looking at Glen Zediker's book on competitive reloading for Highpower for a good layman's explanation/ diagram that explains this phenomena (I loaned mine out or I would post the excerpt) Depending on the bullet, you CAN get a BETTER group at an intermediate range (in my specific experience 300yds dispersion better 100yds , and basically static dispersions from 200 to 300) with long "high BC" (tangent and secant ogive) projectiles. Unfortunately I have never found or heard of one that does better at 600 than 300..... If you are looking for that 1/4 MOA group at 100 USE A SHORT BULLET (should be in the 50-55 gr. range), with or without a flatbase (Sierra 52 gr HPBT matchking has ben my favorite, but Hornady's, Bergers and JLK's work great too). It is much harder to clean a Reduced Course (600 yds reduced to 100 yds) Highpower target with the 75gr/77gr/80gr/90gr that you would normally use at 600. YMMV Jesse
