I ran a Gen 2 Glock mag version in a few matches, but ended up selling it for a few reasons. 1. You can not disassemble the receiver to clean and lube the trigger group. 2. The trigger has a lot of creep, and is heavy. 3. The recoil is very sharp. Adding two 7/8" dia. rubber washers helped. 4. Adding optics is difficult and expensive. 5. The front sight windage adjustment is held in place by a spring. 6. The carbine does not have a last round bolt hold open. 7. The factory picatinny/m-lok forearm had to be shimmed to remove any movement. It was fun to shoot after I replaced the front sight post with a Hi-viz fiber front post, but it was difficult to hang with the AR-9s, MPXs, and CZ Scorpions.

Keeping the new bore concentric to the old bore will be very difficult with a vise and drill press. I've tried and I've ruined. Sent from my SAMSUNG-SM-G900A using Tapatalk

I've wondered why the back of the pcc firing pins are squared off. The standard firing pin is round. Also, standard firing pins to not break as often as the pcc firing pins. Sent from my SAMSUNG-SM-G900A using Tapatalk

What causes the 9mm firing pins to break? Is it the rapid forward and aft cycling of the bolt, interior geometry of the bolt, or the repeated impact of the hammer? I'm leaning more toward the repeated hammer impacts and possible hammer spring weight. If you have had a firing pin break, who was the manufacturer, and what trigger/hammer/spring setup do you have?

It should be in today. I'll mount it at 12, and see how much it obscures the sight picture through the fastfire. The Fastfire is on a lower 1/3rd mount. Sent from my SAMSUNG-SM-G900A using Tapatalk

I'm loading a 124gr Xtreme flat nose, over 4gr of TG, seated to 1.14" for my Glocks and 9mm AR. I'm consistently getting 1" groups (5 rounds) at 50 yards. The AR is a KVP/Faxon reamed 16" barrel. I need to shoot for groups and drop at 100 yards soon. Sent from my SAMSUNG-SM-G900A using Tapatalk

I ordered a Crimson Trace 206 for my 9mm AR. It will be secondary to my Fastfire. Where are you mounting your lasers; 12 or 6 o'clock, 45° offset? What distance are you zeroing the lasers? I've seen where a few guys have zeroed at 10 yards. Currently I'm thinking 12 o'clock, zeroed at 10 or 15 yards for USPSA and outlaw speed steel matches.

Sure it's not lead and carbon build-up? It happens if you are shooting cast/coated/plated bullets in a rough bore or with hot powder. If your comp caught a bullet, your comp would be down range. Or part of your comp will be down range. Sent from my SAMSUNG-SM-G900A using Tapatalk

I've thought about the Korean Glock drum, but haven't seen or heard of enough people running drums in matches. Sent from my SAMSUNG-SM-G900A using Tapatalk

124gr Xtreme plated over titegroup, 1.14" oal, is consistently grouping 1" at 50 yards out of my carbine. Sent from my SAMSUNG-SM-G900A using Tapatalk

Chamber doesn't suck, the short throat sucks. My reamed Faxon/KVP barrel is grouping 1" @ 50 yards with my handloads, and has functioned 100% Sent from my SAMSUNG-SM-G900A using Tapatalk

I ended up buying my own Manson reamer for my KVP barrel. I could not find a place that would touch a nitrided barrel for a cost less than a reamer. It was tough. Ended up having to pull the barrel, and use a drill motor. Once you break through the finish, it's a little easier. Sent from my SAMSUNG-SM-G900A using Tapatalk

My Google skills are not working today. I can find restrictions that limit rifle muzzle brake/compensator sizes, but I can't find anything about Pistol Caliber Carbine muzzle device sizes, for any of the shooting originations. I found a comp I like, but it's .90" dia. I'm wondering if I should stick with a JP or SLR that are .84" dia. Thanks Sent from my SAMSUNG-SM-G900A using Tapatalk

Found this on eBay, looks tempting for the price. http://www.ebay.com/itm/152415986094 Sent from my SAMSUNG-SM-G900A using Tapatalk

Your hammer spring might be too light to power through the firing pin springs in the bolts. It has happened in my AR9 and .22lr AR's. Sent from my SAMSUNG-SM-G900A using Tapatalk

The throat (just past the chamber) is too tight. Go back and read the threads about reaming barrel throats in this forum. I had to open the throat in my KVP/Faxon barrel. Sent from my SAMSUNG-SM-G900A using Tapatalk

The end is not square, I can't remember if it's 1/4" or 3/8" dia, a friend is borrowing the reamer. But it has a flat for the a set screw. Sent from my SAMSUNG-SM-G900A using Tapatalk

The Manson reamer direct from Manson (you have to call them) is $40 with the solid pilot. The T-Handle extension is $16, if you don't want to pull your barrel. I ended up having to pull my Faxon/KVP barrel and use a drill motor to cut through the nitride finish. Sent from my SAMSUNG-SM-G900A using Tapatalk

We've seen punctured primers, failures to feed and eject, and firing on trigger reset. That's with three different sbr'd MPX's, each having one or two of the failures listed above. Sent from my SAMSUNG-SM-G900A using Tapatalk

JP barrels are too heavy.... Sent from my SAMSUNG-SM-G900A using Tapatalk

I reamed the throat Saturday. I learned the melonite finish is difficult to start cutting. I ended up going deeper than planned, but I didn't loose any accuracy with factory 115gr, or my 124gr 1.145" handloads. Sent from my SAMSUNG-SM-G900A using Tapatalk

Sig MPX's choke mid match than any other platform at our matches. CZ's and quality build AR's run fine. Sent from my SAMSUNG-SM-G900A using Tapatalk

You think Faxon/Kaw Valley and PSA would have noticed by now. I ordered a Manson reamer and t-handle a few days ago. It looks like I might make my money back. A few USPSA and IDPA guys in my club want the throats in their CZ Scorpions and PSAs opened and lengthened. Thanks for the help. I've spent too much time on here reading about throats and buffer weights. Sent from my SAMSUNG-SM-G900A using Tapatalk

Bamboo, I've spent a lot of time reading your thread. Will the extra .001" make a difference? I only shoot plated and sometimes jacketed. My last search for a Clymer 9mm reamer came up as sold out. Will the new throated area wear faster? I'm assuming it's not an issue being this is a pistol caliber. Aircooled, being a used KVP, I would be thrilled to get $100 shipped for it. Right now I'm leaning towards reaming the throat. This barrel is almost one hole group accurate @ 25 yards, but the good groups are 1.75" and bad are 4.5" @ 50 yards.

I have a 16" KVP/Faxon 9mm barrel on my PCC. It groups 115gr WWB and my 124gr titegroup Glock load very well at 50 yards. It does not like my various 100gr, 115gr, 147gr loads that work for my Glocks. The 124gr load is too long for the throat. I'm debating on buying a Manson reamer, or replace the barrel with a JP. Only cons with replacing is the added weight of the JP vs. KVP, and I already know my head space is good with the KVP bolt and barrel combo. If you have reamed a Faxon/Kaw Valley barrel, did the finish cause and problems or chatter? Thanks Sent from my SAMSUNG-SM-G900A using Tapatalk
