Kimber 84L Montana light primer strikes and a new spring

I had several light primer strikes with failure to fire last year leading up to the fall so I decided to not use my Kimber Montana and put it away for the rest of the year and work on it in the off season. I measured the pin protrusion and it was .055 and that's considered good and on the top side of max so I cleaned it up and polished the pin but decided since it was all torn apart I would put a new spring in it. So a phone call to Kimber and $18 later I have a new spring in hand. Can't help but notice the length difference of the new one vs the old one with probably less than 500 shots on it but it's a solid 7/16 longer.

Just a share

I would say they changed the design

Never under estimate the internet community's ability to reply to your post with their personal rant about their tangentially related, single occurrence issue.




What I have learned on AR, since 2001:
1. The proper answer to: Where is the best place in town to get a steak dinner? is…You should go to Mel's Diner and get the fried chicken.
2. Big game animals can tell the difference between .015 of an inch in diameter, 15 grains of bullet weight, and 150 fps.
3. There is a difference in the performance of two identical projectiles launched at the same velocity if they came from different cartridges.
4. While a double rifle is the perfect DGR, every 375HH bolt gun needs to be modified to carry at least 5 down.
5. While a floor plate and detachable box magazine both use a mechanical latch, only the floor plate latch is reliable. Disregard the fact that every modern military rifle uses a detachable box magazine.
6. The Remington 700 is unreliable regardless of the fact it is the basis of the USMC M40 sniper rifle for 40+ years with no changes to the receiver or extractor and is the choice of more military and law enforcement sniper units than any other rifle.
7. PF actions are not suitable for a DGR and it is irrelevant that the M1, M14, M16, & AK47 which were designed for hunting men that can shoot back are all PF actions.
8. 95 deg F in Africa is different than 95 deg F in TX or CA and that is why you must worry about ammunition temperature in Africa (even though most safaris take place in winter) but not in TX or in CA.
9. The size of a ding in a gun's finish doesn't matter, what matters is whether it’s a safe ding or not.
10. 1 in a row is a trend, 2 in a row is statistically significant, and 3 in a row is an irrefutable fact.
11. Never buy a WSM or RCM cartridge for a safari rifle or your go to rifle in the USA because if they lose your ammo you can't find replacement ammo but don't worry 280 Rem, 338-06, 35 Whelen, and all Weatherby cartridges abound in Africa and back country stores.
12. A well hit animal can run 75 yds. in the open and suddenly drop with no initial blood trail, but the one I shot from 200 yds. away that ran 10 yds. and disappeared into a thicket and was not found was lost because the bullet penciled thru. I am 100% certain of this even though I have no physical evidence.
13. A 300 Win Mag is a 500 yard elk cartridge but a 308 Win is not a 300 yard elk cartridge even though the same bullet is travelling at the same velocity at those respective distances.

It could easily be a different design spring. On the other hand a spring will often take an early "set" and stay there. Years back I was speed locking a model 70 with light firing pin and what was supposed to be some high tech spring. Tubbs sold them or lent his name to the project. Anyway I changed everything out, and a short time later had some reason to take it all apart again. I seem to remember it was working on the safety cut out. Anyway, when I had it out I set it against a brand new spring and it was considerably shorter. I think it's normal.

Brownells used to sell increased force springs for Kimbers, maybe they still do.

I think Dogleg is correct. It looks like the same number of coils to me. Buy the stronger one from Brownells, or do what I did and get rid of it. I could never get mine to shoot and it was a 308.

I have a Kimber Montana in 7mm08 & love it.

The only complaint I had was that the front sling swivel stripped its thread and came off withing a few hours of using in the bush. A friend had a similar experience & sent the rifle back.

I just glued it back with epoxy.
