Feed lips and follower..
.......just reminded me to check over on the Girls & Guns thread.....
Perhaps the WHY behind the WTF!!!!
The Chip McCormick mag.’s Slide Stop actuator sits higher in the gun with one round left to go than the other brands by the following amount.
.071”-.074” higher than the Colt
.069”-.072” higher than the Dan Wesson
.051”-.054” higher than the Mec-Gar
This very well may be why it can activate the SS with one round remaining.
It is the only design that can easily change the actuator dimension relative to the follower/bullet surface. With minimum squeeze pressure… or even spring tension. (see pics 4,5&6)
***NOTE*** all mags are of low round count. This is not a proven method of comparison…. However, it convinces me that McCormick .38 super mags are not worth buying.
Damn that’s funny
Had Tripp make .38 super and 9x23 mags for my LB Super Stinger. They work flawlessly.
Just ordered 4 Tripp .38 sup mags yesterday.... I hope they do the trick... I'm tired of dealing with half-the-time-function.
I've never owned a bunch of 1911s at the same time, but when I built any pistol (carry or race gun), I always tuned the pistol with a set of mags to be used with each other. Never expected a mag to work right out of the box, but then I never expected a 1911 to ever work right out of the box.
You would think that with today's tech, that everything would be plug-and-play, but given that many 1911 factory and custom builders do their own thing and don't give a darn about interchangeability of even the most basic parts we end up right back where we were decades ago. Isn't life grand.
I only use the Chip mags in the .38supers we build here and never have a single issue. Perhaps it's the guns...
Great comparison and dang you got some nice tools..
Probably Joe..... its often observed here that if it ain't Joe's, it ain't sh*t!
But I try to make due with what I have. *sarc.
From a purely engineering point of view, the follower on the left (Chip)
Has the least integrity for maintaining a constant dimension between the two functioning surfaces. A variance of just a few ponds of pressure can compress or open up that distance. The design of the other two are much more efficient at maintaining a constant set dimension.
In the event that Joe builds me a gun... I will request something other than Chip mags.
Collector, what do your CMC mags look like with 1 round loaded? Where is the slide stop engagement shelf?
^^^^ I don’t care for that style follower (the left one) at all.
I just bought some Wilson 10mm mags and really like them. Have you tried one of their mags? Just curious.
The CMC follower is split to stuff an extra round in the tube. You should probably send an email to them to see if there have been any issues with their followers https://www.cmproducts.com/crm.asp?action=contactus
I know lots of folks who swear by their 38 mags
I went to the Chip McCormick web site and looked at that magazine specifically.
On the same page there are 4 recent reviews on the 38 super mags. All give a 5 star review on them. I would call customer service and ask to speak with a tech and see what they say.
Sorry forgot to the http link.
The pic below shows the Chipster mags with one round in it. The bottom mag is how both mags were as purchased. Yes ... that shelf is high enough to engage the SS on EVERY .38 sup I own. WC, NHs, EB, Colts (KGBs included), DWs & JEMs.
Probably a Joe Cs if I had one.
The top mag is after I disassembled and tuned (fancy word for bend) it to where it works in ALL my .38s.
Thats what I would do
Have you been to the range since tuning the mags? I’m interested and concerned if they still stay tuned to your spec after full mags of 10 and one in the pipe or 11 rds to start with.
Let us know. Thx
Thanks for the links... I used their contact form to share information and photos.
