Is the 10mm less reliable because of the case length?

    I assume the .357 Sig's bottle neck design make it feed more reliably. Are the other Glock calibers any more or less reliable because of their size? I am considering 10 mm now that Federal finally has a HST for it.

    Think he means n general reliability.

    They are reliable.

    Simple answer NO. Adding more complexity...You are considering it now just because federal finally has something you like for it? Many of us have been shooting 10mm *RELIABLY* for many years without federal anything. Please ask another question.

    A few thousand rounds through my Ruger SR1911 10 mm, I have never had any problems.
    I guess it depends on the gun.

    Nope. Shoot, reload, and enjoy.

    No. Do some research on the 10mm and your concerns will go away.

    I’m sure reliability is fine.

    But 10mm HST won’t really do anything for you that .40 S&W HST won’t do.

    Except give you more recoil to contend with while trying to shoot fast and accurately.

    Thers' nothing inherent to the cartridge design that would cause feeding problems. A 9mm is a straight walled rimless case just like the 10mm with the only difference being that it's a shorter cartridge but its chambered in a gun that has a proportionally shorter chamber and it feeds from a proportionally shorter magazine.

    You can't compare the 357 sig to the 10mm but you can compare it to the 40 and both feed with equal reliability but bottleneck cartridges sometimes have feeding problems if the follower doesn't guide the cartridge upward into the chamber. This is a problem peopl ehave had with feeding bottlenecked 9x25 Dillon out of 10mm magazines.

    I've had a Glock 20 SF for over 10 years now an have fired thousands of rounds of all different ammo through it including 40 S&W ammo and hot Underwood, Buffalo Bore, and Double Tap ammo, as well as reloads, and I've never had single malfunction.

    The Federal 200 grain HST is an excellent load for the 10mm.

    I assume you're (OP) concerned with the longer case having to go up and into the chamber, then fully feed to battery. Since the cartridge cannot bend in the middle, it may seem logical that it could hang up more than a .40 S&W, which is why some believe the Sig would feed more reliably because it is smaller on the boolit end and lets the cartridge 'bend' more to fully chamber. My personal, simply answer is the case length difference between 10mm and .40 isn't much and the angle from the mag to the chamber isn't steep...it's almost straight in. I believe this is the main reason Glocks feed better than many other handguns simply because the cartridge doesn't have to try to feed at a sharp angle. Short answer is no, they got it tuned before it left the factory.

    Had a glock 10 mm and it was great. My kimber 1911 was a total POS. If you are looking at glock I wouldn’t worry too much. The g20 is a great gun.

    I have to disagree here. The 10mm is a potent cartridge with a heft recoil. The recoil is moderate in comparison to a heavy revolver round like one of the mity magnums or 45C. However in a bottom feeding SA the heavy bullet and relatively long case allow the inertia of the loade round to tip forward and down. In the double stack magazine with really heavy loads this can allow the slide to slip past the cartridge rim and cause failures to feed. If the loads used are lighter than 10 grain bullets or velocity say of the 180 gr to stay in the realm of 1250FPS then feeding is flawless. Or in a single stack magazine like the P220 you cant make it not feed.

    Ive gotten into this realm of high energy rounds just trying to find out what is needed to comply with some states r(MD) requirements of KE to hunt game such as deer. Moderate loads(still with KE higher than almost all other SA) asolutely no problems. Nuclear loads, then reliabilty suffers.

    Not isolated instances, but not talked about either.

    I have noticed with Glocks and 10mm 1911's, you do have to maintain a tight wrist lock when firing full power ammo (Underwood, Buffalo Bore). With the lesser powered ammo this is not as critical, and would be the same as for a .40 caliber Glock.

    This holds true for myself and my shooting buddy, who has big arms and huge wrists. There is an inertia / biological aspect to it.

    But purely mechanically speaking, the 10mm is just as reliable as any other cartridge IMHO.

    When I first got my G29 and was firing buffalo bore ammo, I had some problems with stove piping. I discovered that I was limp wristing the weapon. I learned how to hold the weapon properly and the problem cleared up.

    I have a G20 upper that I run on a G21 Gen 3 lower. Runs 100%.
