CaldwellUniversal Pistol Loader with Adjustable Magazine Setting and Multi-Caliber Operation for Easy Loading Single and Double Stack Magazines for Target Shooting, Competition, and Range

It works as advertised. Versatile and easy to use on different size mags. I’ve only loaded about 5 mags with it so I can’t speak to durability but so far so good. It had a quality feel and works well.

This mag loader looked a little over complicated and intimidating to me at first, but once I figured out how it works, it’s really simple and works GREAT. It fit my CZ P10c mags beautifully on setting 4, just make sure that the mag is pushed down AS FAR into the slot as it can go before tightening the knob to hold the magazine. If it isn’t seated down as far as it can go, the loader will not press the round into the magazine and might even cause a round to get stuck in the magazine. You will know it’s now seated right before you get a round stuck in your mag, but just wanted to mention that after I muscled it and did end up getting a round stuck lol. After that, just throw a round into the little port, squeeze the lever decently hard (the lever has 2 actions, one to press the round “down” in the magazine towards the follower, and the same lever presses another lever that pushes the round “back” into the magazine) and load the next round!It works great for 9mm. I tried it with a G30S (45 caliber double stack glock mag) and it did work, but it took significantly more force and I wasn’t sure how well it would hold up loading a ton of these. I’ll probably stick to hand loading my .45 carry and use this for my 9mm for competitions. It’s great because you can operate this with one hand while you grab and ready another round, I highly recommend this if you’re loading a bunch of mags and want to save your fingers!

Loader works really well. I have Arthritis and was unable to load my magazines fully now I can fully load a 17 round magazine. Load my wife and daughter's 380 magazines. You have to play with the adjustments a little.Take your time and make sure it's centered

When it's set up, it works well, up to the last couple bullets in a 13 round, 9mm clip. Then, they don't always want to press down on the others in the clip.Setup is important. It amounts to getting the clip in the correct position for it's size and width. It would be nice to be able to lock this down, though, if you have different clips, calibers, it might be easier to just color code the side adjustments.When it's working for an older clip, things go without a problem. I think it's just the newer, more firm springs in the clips that cause the problem loading the last one or two rounds.

I don't know how long it will last but I'm not leaving home without it.Worked perfect on 9mm G19 double stack and also on Keltec P32 single stack 32ACP.Man this saved my fingers. So fast and easy. It wasn't supposed to go as small as 32ACP but it did just fine. Just tilt it a little bit so the bullet rests properly and use the smallest mag width setting.

The media could not be loaded. Surprised there are so many good reviews for this hunk of junk. I was really excited as a lot of people said it worked well for 2011 magazines. It certainly does not work for 2011 magazines. I can sometimes load 5 or so rounds in a row, but then the rim of the next case gets caught on the front edge of the previous cartridge’s case and won’t seat into the magazine. I followed the instructions to a T tried changing the sizing to different variations, tried it tighter, looser, anything I figured that could make it load more reliably.Trying to load just regular federal HSTs. Will absolutely be returning and just sticking with loading by hand. A lot less hassle.

I have purchased a few speed loaders. Up LULO, ETS and a couple very basic plunger types. The ETS won't work on all my magazines. The Up LoLU works, most times. But, feels cheap and, doesn't feel like it is going to last. This Caldwell is a different animal. It is mostly a metal construction. So, easy to use it amazes me. And, it's a fast way to easily load my mags. And, the price is less than the all plastic Up Lolu! Less, by almost 10$ and, works much, much better. The Caldwell works on every magazine of every hand gun I own. Maybe a 40ca would be to big. But, I don't have a 40 cal. So, it doesn't matter to me. If you are looking for a quality speed loader. Look no further than the Caldwell. By far, the best value for dollar. And, they shipped it to me in Alaska in just 4 days! This seller is on top of their game.

I'm not completely satisfied, but will be keeping this speed loader.Pro: I get minimal jamming, with extremely smooth and fast reloading of all my steel magazines.Con: Nothing but issues with all nylon/composite mags.I tested this speed loader on a variety of calibers and types of mags, which included .380, 9mm, .40, & .45 acp.; Glock, Taurus, S&W, KelTech, & High Point.Brand, size, and style (single/double stack) of mag made no difference to functionality of speed loader.If it was a steel mag, it functioned nearly perfectly (I loaded approx 10 steel mags of varying sizes/calibers, with only 1 jam on a 15 round Taurus 9mm mag. Most likely user error.)I never got more than 5 rounds into a nylon mag (hard stop). I tried adjusting the bumpers to move there mag left and right, but never once got more than 5 rounds into a mag before it wouldn't allow more. I tried single and double stacks, mags ranging from 10 rounds to 33 round mags. Regardless of the capacity, the rounds would not feed and they started carving into the mag.Since this works so well with steel mags, which I have plenty of, it will get plenty of use. However, I'm disappointed that I'll still have to fatigue my fingers to I reload my nylon mags.
