So I'm having a hard time understanding this problem here and I'm going to apologize in advance to the other side but here it goes. If 1600fps out of a stock glock barreled 40sw is doable then what's the point of the 10mm. Just trying to wrap my head around this. How is the parent cartridge weaker then its cut down offspring? I'm getting case bulging long before I get anywhere in that general ballfield. Am I missing something? Did I buy the wrong gun? Should I sell the 10 and get a 40? Again I'm not trying to be mean to another member just asking if I have been using the wrong cartridge.

Who is SAFELY getting 1600fps out of a .40S&W? From what I've heard, 10mm brass has stronger web area than .40S&W, and the additional case volume is definitely a plus. I can get 135gr bullets to 1600fps from my 3.78" G29 STOCK barrel, and do it safely. Do you know someone who can beat (or even come close to) that with a .40S&W? If so, who and how?

I've heard of people hot-rodding the .40S&W, and some claim that the web is stronger because it uses small primers. However, I think that's just asking from trouble. Please fill in the gaps, because I'm confused where you're getting this information of a .40S&W being capable of that velocity.

Go to the general glocking section and check out the 20 vs 21 thread. It rather surprised me because its a fellow 10 ringer. I do belive we were talking about 180 gr bullets but it quickly developed into a ipm. Im just trying to check my facts. If I am wrong I wish to apologize to him. I just don't think I am and need some confirmation

I just found it by looking at your last posts. I posted there. Are you talking about the Jdog guy? If so, he's quoting 10mm ballistics, not .40S&W. What he was saying (very unclearly) is that he shoots .400" bullets at those speeds. He did not mean he was using a .40S&W, but rather a 10mm. Both .40S&W and 10mm shoot the same bullets, that is .400" bullets. If you are pushing a .40S&W to 1600fps, you are either using an insanely light bullet, or you are on the verge of blowing up your gun.

Ok that's what I thought it just wasn't makeing any sense to me because he kept saying 40 cal. I know people are doing crazy things with them and decided to ask the experts. I'm not new to guns I just like staying semi quiet until I'm sure of my facts. Cause somehow I can still feel embarrassed through the internet.

Honestly, I think he's confused. I just asked him which caliber he's shooting, and I'm thinking he's gonna say .40S&W. Maybe not, but I think he thinks .40S&W and 10mm are the same because they both use .400" bullets. I guess we'll see if he answers.

He was talking about 10mm, not .40S&W.

You did not buy the wrong gun. Starting loads for 10mm are about where 40 S&W max out. The "FBI Load" is really warm for a 40, but pretty wimpy for a ten. The 10mm can do everything that a 40 can do, and then a lot more.

Rest assured. You got the real deal.

I saw. He confused me pretty badly. Particularly since we were talking about 40 short and weak when he started throwing out those numbers. I do believe you are correct that he thought 40 and 10 were interchangeable. Hope he never makes that mistake while loading mags! Was I correct about no flocks with fully supported chambers?

He had me confused also, I thought he was talking about .40sw, and didnt he mention having a G22? Oh well...And yes, you are correct, no Glock barrel is "fully supported"

Pretty much. I think the 9mm and .357SIG Glocks have pretty well supported chambers. The 9mm is that way because it has a tapered case; the .357SIG because it's a necked cartridge. However, I don't think any Glock is what you'd call "fully supported".

I didn't look at the thread, but these are the woes of posting on the internet.

Unfortunately.
