I'm working on a product evaluation for Tripp Research. They provided me with some of their 8 round 8R-45-RG Cobra Mags. If capacity is not an issue they have the same high quality 7 round mags.
Tripp Research, Inc.
Read the information provided on their web site. They have taken a full bore technology approach to mag development. The real difference, IMHO is they are in the business of quality magazine production. It's their only product, unlike others who make guns and oh by the way some mags to go with them.
I've got to tell you, these mags are some of the best I have run in the XSE.
I am holding off claiming them THE
best until I get some more rounds downrange but after about 500 I have yet to have any problems! I have shot them just like I test any new gun I get. I start with one round, rack it to battery and shoot looking for ejection and slide stop. Next is two rounds looking for feed, eject and slide stop. This goes on up to a full mag + 1. That's 45 rounds spent for an 8 round mag test. Nearly a box of ammo to complete my test on one mag!
At this point I can tell you to get a couple of these and work them out. I'm confident you will be satisfied!
Give Sherri @ Tripp a call 1-877-837-9445 and tell her you talked to canebrake on the firearmstalk.com forum. She is extremely knowledgeable and can answer any questions you have. If you want to go straight to the horse's mouth you can ask for Virgil Tripp and he will be glad to talk tech with you. Try that at Colt, or Wilson Combat!
I need to say I have had little problem with my 8 round Colt mags for the XSE. The 7 round Colts for my Defender have given me some FTF and FTE issues.
I corrected the Defender problem with a pair of Wilson Combat 47DOXB, 8 rounders and the problem is history. That was before I discovered Tripp Research.
When I got my XSE I had ordered a Wilson Combat 500B, 8 round ETM in anticipation of problems with the stock Colt mags. I got the EMT because I have installed a mag well and wanted the larger base. I had no problems with the stock Colt mags or the WC ETM. The XSE runs well with all 45 ammo I have used including HPs.
Bottom line, when I use my engineering experience to compare the three different brand mags, the Tripp Cobra mags are hands down the best built period!
When my Defender returns from the refinisher, I will test the Tripp 8 rounder for function where the Colts had a problem. What I have experienced to date, I think they will pass my scrutiny with flying colors. At that point I will declare a winner and will more than likely buy only Cobra Mags for my Colts in the future!
