Description:

Ensure Safe Function Testing with Inert Dummy Rounds

Introducing the CENTERFIRE HANDGUN DUMMY ROUNDS, GENCO INC. 357 SIG DUMMIES 50/BOX, the ideal solution for safely checking the functionality of your firearms.

Product Description

Manufactured to exact specifications, including diameter and length dimensions, weight, and balance of factory loaded ammo, these DUMMIES possess the proper functioning characteristics to reliably check:

Magazine feeding
Action timing
Extraction
Ejection of all guns

The only professionally accepted and safe way to check gun functioning; live ammo should never be used except in actual test-firing on the range - after you have checked the gun with DUMMIES.

The very reasonable cost per DUMMY is an added incentive to use them regularly. The blackened case makes them distinct and instantly recognizable as DUMMIES, making them ideal - and safe - to use as a sales aid. They are especially useful when demonstrating how a particular gun functions or in gun safety instruction classes.

Using DUMMIES absolutely eliminates the chance of an accidental discharge, ensuring a safer environment for all.

Top takeaways

GENCO INC. 357 SIG DUMMIES are designed to the exact specifications of live ammunition for reliable testing of magazine feeding, action timing, extraction, and ejection.
Using DUMMIES is the professionally accepted and safe method to check gun functioning without the risk of accidental discharge, as opposed to live ammunition.
The blackened case of the DUMMIES makes them easily distinguishable from live ammo, making them safe and ideal for demonstrations in sales or gun safety instruction classes.

Definitely recommended

Well designed, well made & well worth it 23/09/2017

I've bought over a dozen brands of dummy rounds and found these to be the best in shape, weight, durability and reproduce the action of real ammo during malfunction drill racking more precisely. Other brands here are either too light, of inaccurate dimension, made of material that lacks durability and will often fragment into your firearm, feels wrong in 'heft and has unrealistic friction co-efficiencies. While Brownells Dummies may lack the 'safety colors' of kindergarten crayons, I think only a very unobservant or rash gunner would confuse a real round with these. Highly recommended.

Avoid These! 17/08/2015

Not the kind of quality I've come to expect from Brownell's. The absence of a dummy primer makes use in a lever gun's tubular magazine nearly impossible. The soft nose bullet hangs up in the hole where the primer would be. This damages the soft lead bullet, jams the gun and causes the bullet to loosen in the cartridge case. I even had a few push the bullet down into the case. The lacquer, or whatever it is, coating also flakes off in the gun's action. I've tried these in both a .357 and 30-30 lever gun with the same disappointing results. They might be OK using a stick type magazine or in a revolver - but there are better options.

Great for test feeding, etc. 19/08/2012

Great product, very functional and quality made. However, I had to give this one a 4-star rating, because the description is a bit deceiving. These are simply empty 9mm cases (no primer, obviously no powder) that have been painted black and had a new bullet seated. Though it is not likely to effect function very much, they are NOT the same 'weight and balance' as live rounds, as I found them to be about 10 grains lighter than a loaded 115gr. FMJ round.

In testing, all ten fed flawlessly through a known good pistol when racking the slide manually. The same ten dummy rounds, when fed through a questionable magazine, resulted in 4 failure to feed incidences, with the magazine being the likely culprit.

Overall, still a great product, but if you would rather spend a few minutes of time instead of your hard-earned money, you could likely achieve similar results making a set of your own.
