You are watching: Can you shoot 40 s&w in a 10mm


Is there any reason girlfriend couldn"t just shoot .40SW in a G29 ? I recognize you deserve to shoot .38 special in a .357 mag, also though the cartridge is shorter, so why couldn"t ns shoot .40S&W in a 10mm? i assume over there is a reason, yet I want to recognize what the is. So please be nice.

i gonna guess and also say the .40 can"t headspace in a 10mm barrel cause it"s much shorter than the 10mm. Rimless cartridges headspace on the instance mouth.this is in reality a very an excellent question and also probably of attention to a the majority of people.
Reactions:Bayou
.38 and .357 mag room supported/headspaced by the bigger diameter instance rim. I know nothing about .40S&W or 10mm other than that they are supported/headspaced by the instance mouth. Also if there were no other concerns, the much shorter case would have the ability to move too much forward in the chamber (if it escaped the extractor) causing inconsistent fail-to-fires as happens as soon as a .380acp is chambered in a 9mm.
From my research... The consensus from those who have actually actually tried that is that it works fine. The extractor will organize the ring in place. But, it will be weaker than it otherwise would be, because of gasses escaping native the too much headspace. The being claimed - ns personally reduce $100 because that a .40 conversion barrel to put in my 20 and also it works great.

Some of the guys in USPSA that run G20"s shooting 40S&W load long. The extractor will hang on come the case and also it will certainly run fine.Not the exact same as a .380acp vs 9mm. The base and also rim that the 9mm are .391" vs .374 for the .380. Likewise the neck is .007" smaller on the .380 and it"s a straight wall surface case. That"s why the blows smoke in a 9mm chamber and can"t hit anything. That"s no the same as the 10mm and 404S&W which are the very same dimensions except for length.

No, no, and no. Shoot 40 in a 10mm may damage the chamber. Among the 10 safety rules of guns is constantly use correct ammunition. Don"t think about, execute "t even comment on it, and more important DON"T do IT.
So in summary. Have the right to you shoot .40 S&W out of a Glock 20...yes. Need to you shoot .40 S&W out of a Glock 20... No No & No.
It"ll carry out in a pinch in situation of emergency prefer running the end of 10mm ammo yet have 40sw ammo.I"ve researched it and lots stated no problem however accuracy will certainly suffer. Also said the no damages was done to the chambers. I"ve read otherwise so i guess it depends on the gun, is it good or cheap.
Given that the 40 S&W is merely a short 10 mm Auto (please refer to the SAAMI traditional below), as long as the 40 S&W cartridge doesn"t "jump" the extractor and fail to fire, it"s the exact same as shooting a 38 one-of-a-kind cartridge in a 357 Magnum revolver... Actually, it"s prefer shooting a 357 Magnum cartridge in a 357 Magnum revolver, because neither the 40 in the 10 no one the 357 headspace top top the instance mouth.ANSI/SAAMI Z299.3 - Centerfire Pistol & Revolver - 2015http://www.saami.org/specifications_and_information/publications/download/205.pdfBest regards,Bob
To shoot "fast and also accurate", push the trigger without moving the pistol and also minimize the pistol"s movement during recoil.

The difference between the 10mm and also the 40sw casing is 3.6mm in length. That"s 0.142" no a entirety lot.It is comparable to shooting 38sp in a 357 yet not the same. The revolver has a forcing cone yet not the semi-auto pistol.
As lengthy as the 40 S&W cartridge headspaces top top the extractor and also the primer ignites... Sending out the bullet on that way... Whatever else is semantics and also inconsequential.It"s that simple.Bob

Anecdotal comments from Calguns.net...can you shoot 40 S&W in a 10mm gun?http://www.calguns.net/calgunforum/showthread.php?t=135850
In the soul of "I wonder what will happen..." i fired a .40SW ring in my 10mm 1006. It chambered, fired, and ejected fine. Ns loaded a magazine through .40s and fired every no problem. I then went v a crate of .40s no problem. Do I introduce anyone else doing it? Nope, but it worked for me ok.

The highlighted comment reflect my personal position as well.Although I"ve never read of a "kaboom" shooting a 40 S&W cartridge in a 10 mm Auto pistol, since the inside wall cup is a few thousandths of one inch shorter than the difference in case lengths, in theory, yet unlikely, press "blowback" seems possible... And also should be avoided. (I important don"t understand just how that would certainly happen, but I"ll let who else discover out.)Best regards,Bob

I"ve checked out the dummies shoot 9mm our of 40S&Ws. Doesn"t hurt the gun, smokes a little, not accurate at all, and also makes a really weird looking case bulge... I recognize guys that run 220 serial 40S&W come 10mm OAL every the time. Doesn"t provide as much length for the cartridge to cave on to, however it functions fine.Here is a tiny blip native Benoshttp://www.brianenos.com/forums/index.php?showtopic=125395
Your"e not going to KaBoom a 10mm v a 40S&W. The is caused by excessive bullet setback, not excess head space. A setback of just .100" in a 9mm will twin the pressure. And also you won"t erode the chamber either, not at 1,000 fps. Yea, at 3,200 fps in a rifle. Virtually forgot, that was some time ago, I carried a G20 for numerous years, and ran at the very least 4-5 instances of 40S&W ammo thru it for qualifications and also practice. It works fine, no as specific as 10mm in ~ 50 yards, yet at 15 yards, no difference.
Old thread and also several different opinions, however I’ll include a data point, that I’ve shot hundreds of 40 cal reloads the end of mine 10mm G20 through its stock barrel. No troubles for me in ~ all. I have actually multiple 40’s, cheap brass and also keep numerous that ammo. No large deal leaving some brass at the range, 10mm brass I’m an ext careful around trying to cave on to. Once I shoot yes, really 10mm, the loads are heavier and also used in both the Glock and also 1911.
From my research... The consensus from those who have actually actually tried that is that it works fine. The extractor will organize the ring in place. But, it will be weaker 보다 it otherwise would be, due to gasses escaping indigenous the excessive headspace. The being claimed - i personally dropped $100 for a .40 conversion barrel to put in my 20 and it functions great.

How would certainly gases escape? The instance is the very same diameter together a 10mm. Is over there a vent in the front of the room that i don"t understand about? my 29 shooting 40"s just fine and also they chronoed as they should. Power and accuracy are simply fine, and the weapons have no issues at all. I"ve operation 1000+ 40"s v my 29 and also no trouble what therefore ever. Too many of civilization do it.Damn it, I constantly fall for the old threads lolI don"t phone call anyone come shoot 40"s from your 10"s. I simply tell them the hasn"t hurt mine yet.
