I have a Gen 4 Glock 29 with a stock length KKM barrel. I am wondering what grain bullet load is the most ideal for the short-barreled G29 for self defense carry. 155? 165? 180? 200?
I've done some searching but didn't find anything conclusive. I have a good selection of factory defense ammo on hand. Seems like the smaller grain loads would have more muzzle blast and incomplete powder burn and the larger bullet loads may not get enough velocity in such a short barrel.
155 or 165 Gold dots would be a good choice...not knowing what the list of ammo you have on hand we can't steer you on which would be better. ::)
Is there a rule of thumb for bullet weight and short barrels?
I have Hornady Custom XTP 180, Hornady Critical Duty 175 Flexlock, Hornady Custom Defense 165 FTX and Sig Sauer 180 VCrown on hand. I will buy whatever weight is ideal.
Any of those would work well and the Sig V Crown would be a great choice too!
Right now my G29 is loaded with Winchester Silver Tips 175r.
My rule of thumb is simple.
My short barrel 10mm is still delivering more energy than a service pistol sized 40 S&W. :))
Just reloaded my G29 with 165 gr Gold Dot from Underwood.
I carry in my G29 Underwood 140gr Lehigh Defense Controlled Fracture projectiles. 1350 Fps

The rule is that there is less velocity from a short barrel, plain and simple. You need to make sure the bullet opens up at those velocities. Since 10mm tends to over-drive most mid-weight bullets when pushed to the max, it could be perfect for the G29.
I think 200g bullets might be marginal, 180's should be ok, and 150 to 165's would seem to be ideal. If you can find them loaded with a slightly faster powder (Pistol Power instead of AA #9) it might be an excellent choice.
I like Gold Dots. They should do great in G29 loadings. In the testing I've seen the Hornady flex tips have a problem in 10mm. I've seen multiple pass through in gel without expansion. I'd make sure that it wasn't the case before I'd trust them.

G, I agree with you 100 percent that is why I switched back to Underwood 165 gr for my G29.
Since the 165 grain seems to be mostly Underwood and Doubletap, I'm considering a 155 grain round. There are more of those out there.
I just picked up a box of HPR 200gr JHP from a local store. Now to get to the range and see how they feel in my G29. :)

The 155 grain xtp loaded by Hornady is pretty good.

I have been waiting for Georgia Arms to get their 155 grain Speer hollowpoints back in stock.

+1 to this. It has good ballistics, yet would be more controllable in the smaller G29 platform.
I'm new to the 10mm but my impression of the round for self defense
1) Overpenetration concern
2) Recoil control for accuracy
Any 10mm close to full power with even marginally good shot placement should be devastating.
Welcome to the forum.
Over penetration is mitigated with proper bullet choice. Recoil is there, but controllable, and more controllable with practice.

This is still a handgun round with less than 1000 ft-lb of energy. Devastating is too strong of a word. Be prepared for placing multiple rounds to get the job accomplished.
Over penetration is always an issue with FMJ and any other non-expanding ammo. For hollow point ammo, expect LESS penetration as velocity increases. More energy goes into deforming the projectile and larger maximum expansion acts more like a parachute.
