I've always been told that 7-round magazine springs last longer than their 8 round counterparts. Lately, though, I've been seeing the value of having that one extra round. My question is, modern materials used considered, do 7-rounders really last longer before the springs need to be changed, and if so, by how much?

Don't Think it matters as long as they work in your gun and you keep up maintance

Agree completely w/ both. I want the extra round & I have not been able to tell that another persons 7rd outlasted my 8s.

I shoot a lot, and only use Wilson 47's or 47D's. Eventually the springs weaken and fail to lock the slide back. I replace the OEM's with Tripp Research spring/follower kit, which make it 7 rounds. So, I am happy with 7 round range mags. I do carry fresh 8 round Wilson mags in my carry guns.

Didn't vote,cuz I don't know. But a good Wilson or Novak 8-rounder is just as reliable as the old 7-round magazines.

Like Primers,I use both at the range but carry 8+1.

That's cool,but don't be surprised if we're shooting and I get "something in my eye",or a "bad lot of ammo"...I usually shoot much better,honest!:wink:

I don`t shoot that much, but my limited experience tells me that as long as you have quality mags to begin with, and perform any usual necessary maintenance, the 7 vs 8 is pretty much a non issue. I use both. 7 rds for my SA GI, and 8 rds for my S&W.

In theory, I suppose 7rds mags offer a more stable platform all-round. In my case however, I can't seem to find a mag that my Les Baers don't like. 7rds, 8rds, 10rds... regardless of make, model, metal, color... They run everything the same... no issues.

I have a dozen Wilson 47DE that I use for competition. I have six others, 47D, that I use some for carry and range work. I have a Check Mate 7rdr with a Tripp kit that I use for deep concealment, as it has no bumber pad. I have five Baer 8rds mags that run great. The OEM springs in Wilson mags are junk, so I watch them closely and replace with Wolff +5% springs at the first sign of malfeasance.
