What is hood chamfer? Is it a cut/shaving in the hood?
It is a beveled edge. On the end of the hood, on the chamber side. What was happening to me was the gun worked fine but when I used a combination of Tripp mags and a SWC bullet it would sometimes FTF. With the bullet sitting higher, the top of the bullet would catch on the sharp corner of the hood.

The 45 mags worked flawlessly, but they are 8 rounders. I searched for a video or descriptor for feed lip adjustment and didnt find much. You Tube is great for "how to's" but nothing there i could find. I may have to watch the gunsmith do one first.

Hello: Do you have any 45 magazines? If so try them and see how it feeds. I make the feed lips 0.394" front to back on my single stack mags for 40. That allows the round to sit up higher and feeds better. I also use 45 mags in my 40 SS's. Hope this helps. Thanks, Eric

Have you looked at the hood of your barrel? When I used some Tripp mags they sat up higher and with a SWC the bullet would hit the hood and slow it up. All I had to do was give it a chamfer. Does the bottom of your hood have a chamfer?

Just figured it out on Sunday at 105 degrees in the sun. It was just the thristy grasshoppers and me out there. Berry round nose 180's fed the best, at 1.180 to 1.185 with 3 of the 5 Tripp magazines. Other 2 Tripps nosedived the rounds for FTF. Tried using some very old mags, 8 round McCormicks and those fed quite well regardless of bullet type or OAL. So looks like it is a feed lip issue - which I did not yet correct to 0.394 but will now. Mags are numbered and their functionality was recorded to match up corrective action. Limited 10 here we come. Thanks all!!
Another writer asked about Trojan 9 - I use Tripps 10rnd mags for single stack and they have functioned flawlessly. I've also used his 9 rnd mags in the past when that was there only option (1st gen), and those worked without hiccup too.
-
Did you figure this out?
-
Brand new mags and springs, straight from Tripp. On the other hand, my crusty-rusty-creaky 10+ year old 8-round mags worked great this past weekend with anything I fed. Now I know its a mag issue.
-
When was the last time you replaced mag springs?
-
Thanks. Will double check feed lips on the Tripps and adjust to 0.394. Still waiting on the Berry round nose 180s. Berry usually ships fast - they must have been behind on this one.

Good to know the OAL limit with 40 mags, hopefully the Tripp 40/10mm mags can take the longer round.

Thanks. Used the 1st gen mags previously. Had trouble with those also. On 2nd Gen now.
I think I will sign off here and go order the elevated mag catch in about 5 minutes!
New grips (G10), changed the grip saftey piece out last year, thats about it.
i am praying extending the OAL will do it, and maybe the round nose. Pretty picky gun I tell you.
Will be nice to have the mag catch ready to go though just in case. Probably play wiht the feed lips again if need be\
Thanks a ton everybody - give me a few weeks to make the changes (3 little ones at home - really cuts the live fire time)

A few questions
- is this the first time you have used Tripp 10rd magazines
- are you using an elevated mag catch (EGW makes a great one)
- Besides the barrel being new, what else has changed?
-
Thank you for the ideas - this forum is truly second to none - grateful for the assists and brainstorming. I did notice the precision bullets (hard molly) did a touch better than the plated (fewer FTF). Ramp is smooth adn clean. No buffer - I'll leave those to the open gun guys. GSmith already throated a touch - nottoo much. Been a frustrating year trying to get this gun back into the game.
-
The other thing you might consider is moving away from plated bullets. These days, they are almost expensive as true jacketed. I have seen several otherwise very reliable pistols that choked on plated bullets.
Might be something to try before doing anything drastic.
-
Thank you, excellent idea. G-smith adjusted the feed lips once, might be worth a second look.

14# spring
...
Failure to feed problem not solved yet - bullet fails to leave the magazine and go up the ramp ~10% of the time. Bullet stays in the magazine but has usually advanced a touch. I retract the slide, drop the slide forward and the gun goes into battery.
Based on these two points, I'd suggest a lighter recoil spring - maybe an 11#-12#. I suspect (but could easily be wrong) that your slide is short cycling with the 14# spring because the gun chambers when you manually operate the slide.
It could also be light ammo - have you chrono'd?
No way the 14# spring is heavy enough for the gun to short stroke with major ammo. It would take a 20+ lb spring to do that.
Light ammo is possible, but that doesn't explain the nose dive.
I suspect that the feed lips are too narrow and not allowing the round to sit high enough.
-
Thank you. Have tried a wide range of PF - from 155 to 180+ trying to find a major round it liked. Most were 165-175.

Thank you. That is what the gun smith suggested as well to start with.

I would try seating your bullets out to 1.185 and see what happens. You'd be surprised how much difference that little bit can make on the feeding.

Kimber stainless 2 in 40 with 100K thru it, been reworked a few times - most recently by a top tier gunsmith. Fresh Barsto barrel, ramped, stellar fit job. 14# spring, heavy recoil rod, 10-rnd 2nd gen Tripp mags tuned by the gsmith, no extractor probs. No trouble feeding or dropping mags. Shoots nice, very tight groups. Would really like to shoot it in L-10 and single-stack major but need to get it reliable first.

I retract the slide, drop the slide forward and the gun goes into battery. Have tried 165's, 170's, and 180's: Ranier and Precision Bullets and now Berry - mostly RNFP but also "RS" and FP bullets. OALs to 1.175. My next idea: extend OAL to 1.18 - 1.19. Try round nose bullet from Berry.
Other ideas? I'd hate to send my gun and mags to V. Tripp but I guess thats always an option.

Roger that. Mine look like nosedives. Good to know about the chamfer option.
