Smith & Wesson Revolver Extra Magazines

it is so nice , heavy and good hand

These are just good well made magazines that one puts on built in shell holder

Pros
They mate with pistol and so far no problems.

Cons
None except I wish they would come in silver to match silver models.

My S&W CO2 revolver came with only one rotary magazine. So, I ordered a set of these. They arrived promptly, and they work just fine. I did not encounter any operational problems of any sort. Depending on the type and weight of the pellets you use and how fast you shoot, you can spend up to 40-45 rounds before you lose accuracy due to reduced CO2 pressure. The faster you shoot the sooner you will lose pressure as the CO2 cartridge gets very cold in the process thus drastically reducing the available pressure. That's the way it is. Giving it 5 to 10 seconds between shots will extend the cartridge life; hence, more shots. The price seems high, but the added fun is worth it.

The holes in these magazines are apparently a shade larger than the ones that come with the gun and I have had problems with the pellets falling out while I was loading them. I have found that some pellets fit better than others.

Cons
Some pellets are too small and fall out during loading. With the cooling of the CO2 during shooting, the two magazines that come with the gun suffice pretty well.

If you get the extra mags you can load up 5 mags before you put in a CO2 cylinder.

Pros
Convenient.
