Question: Will these aluminum snap caps damage feed ramps?
Document: These 9mm luger snap caps are great! They are made of machined aluminum and are identical in size of real 9mm bullets. I read other reviews saying that they were getting red shavings in their guns but I am not having that problem at all. They cycle through my pistol and protect from damage against dry firing certain weapons.The centers are made of a hard rubber like material to absorb the shock of the firing pin.
Use these on my 9mm RO.They hold up great to practice use, but DO have a finite lifespan when used with guns with extended feed ramps and metal frames. Will last longer in alloy pistols.
I know the aluminum is softer than the steel of the gun, but as far as I know foreign materials can deteriorate anything especially if you let it stay in between two working mechanisms. It may not damage the gun immediately, but it can contribute to the deterioration of the gun's quality.
These feed much more reliably than the plastic snap caps (that might not be an advantage if you're doing malfunction drills...) and I like how they DON'T have brass-colored bases.
feed and cycle like live ammo, they're nearly indestructible. I like these over plastic snap caps very much. I have painted my capes hot pink for training.
Have used these snap caps before. They work well - feed and eject like the real thing. They do get a bit scuffed up from the magazine feed lips over time, but still function as intended. Would recommend to anyone for practice handling firearms.
They feed and eject in my gun, have dry fired several hundred times and the snap cap is still holding up. Some of the paint has worn away from the edges and I've only cycled one of these caps a couple dozen times. That being said, I haven't seen any chunks of paint come off and can't expect the paint not to wear off a little.
i like to keep my guns well oiled at all times and the oil stays on the snap caps good and if they are re feed into the mag that might make for some feeding problems later you dont want to deal with. if your thinking about getting them i would say yes buy it. they work great if your looking to keep live ammo in your mag and gun off safety. also works great to practicing hustler shooting.
Aside from being on the short side, A-Zoom caps are a cut above most I've seen as they appear as though they'll last. (1.1045" is about minimum where as the MOL can be as much as 1.169. Makes some difference when testing the pistols abilities to feed the heavier round properly) Also, snap caps are a necessity when repeated dry firing is required. These fill the bill perfectly because they load and eject just as the real thing.
Every gun owner should own some snap caps, and A-Zoom probably makes the best snap caps on the market. The set I received are anodized with a red-brown color like most other A-Zoom snap caps, but I have seen some from A-zoom that are more of a cherry red. The work well and feed flawlessly in my Glock and XDM. I mainly use them for dryfire practice, but they can also be included in a magazine of loaded ammunition to help practice clearing malfunctions.
Answer: yes
