Semi-auto jams

How often to semi-auto's jam? I rented a Springfield Champion 45 at the local range and shot about thirty rounds through it and had one jam. That sounds like a high percentage. I assume that is not normal, but what is normal?

That is not normal. But then again it probably has not been cleaned in a while.
There is no set number at what a gun will/will not misfire.One thing is certain----keep those autos clean to ensure reliability. :twisted: :twisted:
Todd, were you shooting commercial loads or the range's loads? Some/most range loads are light and can cause cycling problems. :wink:
If it's clean and well lubricated there is really no reason for it to jam. Paul is right about the range loads sometimes being too light, this can have an affect on the slide action and may cause the gun to not cycle properly.
It was not necessarily a new gun, but part of their rental group. The gun looked like it was in good shape. The ammo was their range ammo, Zero brand 45 230 FMJ C. The gun jammed on the second shot. I recocked it and it didn't jam after that (about 20 more shots).
This is why I love revolvers as much as I do.

A well made and reasonably well maintained semi-auto should never jam unless there is a problem with the ammo. Many times jamming is also magazine related, like with my Llama.
It is possible the malfunction was operator error too, limp wristing would also cause a jam. This is not uncommon with the very small, short gripped 1911s which I believe the Champion is. The description of the problem is a little unclear too, "recocking" leaves me thinking the round did not fire and the hammer was drawn back to be fired again on the same round. This would most likely be an ammo problem and not a gun malfunction especially since the rest of the rounds went off without a hitch. This is not an uncommon happening with some lots of Sellior & Belloit ammo and makes for good malfunction drills. I've seen a couple thousand rounds of various calibers Zero brand ammo used without a problem but a bad round is always possible.
Uglydog makes good point - but the ammo is still a likely cause too. Range ammo sold by the range is typically reloads and depending on who did them can vary greatly. The range near me occasionaly gets a bad batch - one weak round out of a box wouldn't be that unusual. As Paul pointed out - reloads are usually only made powerful enough to cycle the gun to begin with.
