Post by fivefive

Hey guys,

I just ordered a kokusai modelguns S&W m10 revolvers, and wish to dry fire it with rounds in it, would it be possible with inert round or dummy round??

is .38 inert rounds gonna fit at all??
or does it have to be dummy rounds so that it will allow me to dry fire it?? as in the cylinder cycle ??

also, anyone try a speedloader with their revolver?? is it cool?

thanks a lot,

five

I'd say an inert round is a live round that has been "de-activated", a dummy round is a round that has been made to replicate a live round but has never contained any primers, powder or any other pyrotechnical medium.
YMMV

I think that real, inert rounds might be too long to fit some chambers, most of my modelgun dummy rounds are shorter then their live counterparts.

I think we need to ask someone more knowledgable then me...

oh but i read it somewhere that the kokusai modelguns S&W m10 revolver uses .38 round that is exactly the same size as the real .38, which is 9x36mm in size.

and that some1 on this forum has put inert .38 round into the kokusai modelguns S&W m10 revolver, and it fits fine.

but then i just wanna know if i should get the inert rounds or the dummy rounds in order to dry fire it???

As far as I'm concerned, 'inert' just means no live powder. A modelgun cartridge with no cap in it is inert. A real round minus the powder and primer is inert, or minus the powder and with an already fired primer. A snap-cap is inert. A dummy round is inert.

Dummy round, to my mind, is something that's inert and can't readily be made otherwise; all of the above would be dummy rounds except the modelgun pfc cartridge minus the cap, since the round itself isn't designed to be a dummy round, and could easily be 'loaded'.

Aren't model guns made so that real live or inert rounds can't be chambered in them, only the dummy rounds or plugfire rounds will fit?

Sounds pretty dangerous to me there is always the chance a live round may go off and that would really cause some injuries if not death. I know I wouldn't be chambering any live rounds in a replica or model gun even if they did fit the chamber!!!!

The M10 will probably come with a cylinder designed to fire the cap cartidges , however to fit the cartridges with the full heads you`ll require a different cylinder , Franky will sell you one although it will probably required some machining to allow it to fit the new cartridges and work .

did you not read what i said?
"kokusai modelguns S&W m10 revolver uses .38 round that is exactly the same size as the real .38, which is 9x36mm in size."
both dummy round and inert round is exactly the same size.

It's not danger at all, think about it, who can get hold of live round, if you can you are already doing illegal stuff...

Yes you`ll be fine to buy dummy rounds after October .
In addition the dummy rounds have a primer held in with a spring so the hammer pin can strike them as much as you like with no damage to anything .

To clear up a couple potential misunderstandings I see here- the above 'dummy round' seems to be referring to 'snap caps' kinda things, which have either a dummy primer on a spring, or just a shock-absorbing synthetic fake primer, made for dry-firing your real guns.

As for fit; it's entirely possible that you could have a modelgun dummy round that's exactly the same size as a real round of ammunition and still not have a snap-cap or dummy (molded off a FMJ round) fit in it, if there's a 'detonator' or other type thing that protrudes into the front end of the modelgun cartridge when it's in the chamber or something... seems more likely to be an issue for semi or full auto models though; probably not an issue with a revolver.

no the cap rounds without a cap fitted will be fine for dry firing .. Id not try inert rounds as if they have a dented primer in place the hammer may strike this and get damaged

Guys, true modelgun specific dummy cartridges with spring loaded solid primers are available for many modelguns. These spring loaded primers will prevent damage to the typically weak modelgun firing pins. Usually Francky, Shazhib as well as others can source them for you.

yep thats what I`m talking about

these are the .38s for the M10 along with the M10 cap ones



these need a different cylinder to the cap rounds and the buggers dont fit straight away either (well mine didnt) and Mr Dremel had to come out and play

p.s mark did you see the latest MGC MP40 post ...about nuts ?

ow gawd blimey ...er no you have to buy caps and push them in .

if you have a look at the above pic, the round to the far left is a cap round and you push a cap into the end .... pull your trigger and it goes bang this is acheived (as if by magic) because the primer is connected to a rod that is connected to the cap cup and this is in turn connected to your arm bone which is connected to your etc etc.

Striking this primer without a cap in the end will make a sort of a .....click sound .

gettit ...hope so

apologies to anyone if they are affected by sarcasm but I`ve just had some marmite and its sent me daft

abs m10, as in the newer version, cos that's the one which would accept real sized rounds .38 9x36mm... (i think)

thought it would be easier to me to get it from him, since he is based in the UK right?? the vcr bill thingy is coming and importing bullets is fine but the idea ain't that great lol...
does the ones that he sell work ??? as in dummy rounds that allows dry-firing??
