Cross Breed Super tuck... very comfy about $75
2 week return policy (IIRC )

you can tuck the shirt over it ( tho the belt clips will show ) allows about 4" tucked in at holster



The revolutionary CrossBreed SuperTuck holster is the most comfortable and concealable inside the waistband (IWB) holster you'll ever wear. Designed exclusively and patented by CrossBreed Holsters, the flagship SuperTuck Deluxe is hand molded to fit each specific firearm listed. It features a premium leather backing with a molded and mounted Kydex pocket. Versatile for carry options, the SuperTuck IWB holster may be worn comfortably with or without your shirt tucked in - based on your personal carry style. The SuperTuck is designed to be carried towards the rear of your draw side - 3:30 to 5 o'clock for a right-hand draw or 7 to 8:30 for a left-hand draw.

I did a little more research and the issue with lead bullets mentioned was related to the type of rifling used in the barrels causing lead bullets to not engage the rifling well.  Sounds like the latest generation Glocks use a more traditional rifling.

Yes, the rifling is different... polygonal rifling in glocks vs conventional. TMK all glocks use it with some variation of hills/valleys.
The polygonal is supposed to seal better ( smoother barrel cuts ) .

I think the use of reloads and lead were more of a CYA on glock's part to ensure the guns would function all the time..

Either way, it doesn't really lead up more if the right bullets as prev mentioned are used.

I don't own any Glock pistols but I thought the type of rifling they use is not recommended for cast bullets?

It may be in the notes from Glock, maybe CYA,  but just requires knowledge of what your doing... proper size of bullet, hardness, maybe gas check.

have fired many lead only rounds in my G20... no more leading than any other gun .

Reloading / Re: Is 100 rounds a lot??

I use both a full progressive and turret press...
To be honest, I feel the Turret Lee press slows down the process BUT I get more control of the quality as you can easily stop any where in the process without screwing other thing up. Also you can easily use it as a single stage when wanted.

Other side is nothing like a full progressive when you want to bang out a large amount of rounds. ( keeping the powder drop low enough to stay in the safe range with +/- drops )

I can say when working up loads including some pretty hot loads i never saw a case bulge, smiles or any signs of problems. Yes few times i got bit flat primers but again no bulges or smiles.

Would be interesting to see what the case bulge size expands to near base.... with your warm loads.

I see .432 most of the time on a G20/3 ( if they hit .434, I trash them for reloading ) on warm loads.
To compare, my Sig 220/10 never gets near .427

Working the brass excessively makes it more prone to cracking.

PS  really good loading thread powders/expansion/accuracy from a way back.

Finding no issues with the 180 or 200 xtp heads.... in a G20/3 stock
using a bench rest, at 50ft, produce almost identical spread on paper
( but am using BD with them )
#9
As mentioned...
for that price I can load a good number of rounds. Heck, Still about .25 per.

Hi end rounds with the 200 gr XTP and some 800x gets right up to 1200 with ease. ( tho it meters like crap and must be each hand weigh )

I'm in the "if it ain't broke , don't fix it " group...

I'd sit back and just keep shooting the gun and see how it goes. Sounds like you have some of the loadings under control, so enjoy.


Just wondering if you use a gas check on the hard cast head? ( not that needed if proper hardness and sized for barrel )

Reloading 10mm ammo / Re: Pressure signs...
May 13 2023 07:58:17 AM MDT

11.0gr. Blue Dot (max)
CCI 300
180gr. Hornady XTP
Starline brass


Have tested the same load with blue dot in my G20/3 with 20lb spring and my Sig 220/10 stock.

The G20 to me was just on the edge of my feelings of safe,... I lowered it down to 10.8 as my max in the G20.
As to the Sig 220/10 there was no issues at all and I felt it was safe in the Sig.

I would also think along the lines of the 10mm average round today is much weaker on the scale of the original 10mm.
Original was ( IIRC ) 200gr bullet at 1200fps... today the average round is a 180gr bullet at about 1100-1150.

If going to shoot it, there may be less issues with today's loads.

I?ve always liked the nickel plated cases, not that they are necessarily any better

Yes so do I....BUT, have always found nickel plated tend to be more brittle.
Brittle = less reloads before a crack

Last two days just been topping off boxes and shooting in the mornings. I can't load anymore as I am out of boxes to keep them in.

You know, zip lock bags are cheap... load written on bags.   :) :)

What are the key differences between a 9mm and a 9mm P+? +P denotes higher than standard pressure - for 9mm, SAAMI standard pressure is 35,000 PSI. 9mm +P is 38,500 PSI. This higher pressure results in an increase in muzzle velocity, which results in various ballistic differences such as a flatter trajectory.
