Frequently Asked Questions:

Which magazine do I need for my pistol?
-Pistol size is the main determining factor. The size for a magazine can be defined by the measurement/distance (center to center) between the grip screws. Government/Commander/Full sized pistols will measure 3 1/8" inches and Officers/Compact will measure 2 5/8" inches. In the part number the last letter is either a "G" or "O" signifying Government or Officers sized.

Is it bad on the spring to leave magazines loaded?
-No, or "not really" is the correct answer. We have Law Enforcement Officers, conceal carry shooters, and people who have bedside pistols and they leave magazines loaded for long periods of time with no issues. Springs will show the most fatigue from loading/unloading and just leaving them compressed doesn't affect the spring as much as people tend to think. We do suggest you test fire magazines regularly, but leaving Tripp magazines loaded is not a problem at all.

When do I need to change springs?
-The simplest answer is when they start having jams on the last round, or fail to lock the slide back because this is when the spring is fully extended and at its weakest. There are some "pro-active" methods to changing springs so you never have a failure from spring weakening. The easiest way is to take a new spring and use it as a size gauge against springs that are "in use" and you will notice the used springs will shrink over time. The "down and dirty" way is to just watch them "shrink in coils" and when they lose a "whole coil" in height, swap them out for new springs. Most pistols can/will still shoot just fine with springs that have lost 2 coils in height and some pistols 3 coils in height. If you want something a little more "hands on" you can take a starting measurement and a failure measurement and work from there on where you want to change yours.

Do you have to leave Tripp Magazines loaded before you can use them?
-Our Magazines are ready to use right out of the package and you don't need to leave ours loaded "over the weekend" before using them. We properly spring our magazines and give our springs a set before we sell them.

Why won't the slide stop drop on an empty magazine?
-All of our followers have a "front skirt" on them which just means there are pieces of material or "skirts" that go down from the follower in the front and back. This makes our followers "anti-tilt" so they will resist rotation. When a follower engages the slide stop moving upwards it will make contact in the front of the follower. This action wants to push the follower down but its job it to resist this and push the slide stop up and lock back the slide when there are no rounds left in the magazine. Our followers resist being pushed down in the front so they can have a solid upwards push to lock back an empty slide. This means that when the magazine is empty and supposed to hold the slide stop up, it's hard to push it down to release the slide. If you have any rounds in the magazine there is no problem releasing the slide.

Do I need an Alloy Basepad?
-The Alloy Basepad is a cosmetic upgrade. It has some practical uses, but for competition shooters I suggest the Polymer/stock basepad.
