Well, time for a dumb newbie question.

How does stronger mag springs cure a light strike on the primer? I thought light primer strikes was the result of a weak firing pin spring??? (assuming the primer is seated correctly)

As Kraigster suggested I cut one coil of the AGP spring so it would work in the 10rd compact 45scp magazine. It is still pretty tough getting the 13rd in the standard 13rd mag. I tried to use the AGP Spring in the 10rd mag and it was a no go without cutting the spring.

I'd be interested in knowing how the stronger mag spring stops light strikes....I went ahead and ordered some AGP extra power mag springs, like everyone else in this thread has, I've been getting light strikes as well with my reloads, I thought it maybe some high primers..I could'nt feel any when loading the mags up. For $6 it's worth a try, besides, I think the stock mag springs are on the weak side anyway. Maybe that mag loader in the XD gear will come in handy after all...

i don't see what the big deal is with the AGP springs. they caused me many malfunctions, FTF's if anything. i'll go back to stock springs and see if there are still issues, but i'm not gonna try to fix something that ain't broken. we'll see. i started using my brand new XD with AGP springs from the get go. i'll have to give the stockies a fair chance to perform.

Being of a mechanical mind I can't pass this one up.

Your theory has holes in it. You still cannot think of the reason that a strong mag spring would help your firing pin. The only the the mag spring does is pus the bullet up. it doesn't put it forward, just up. Getting it up faster or harder isn't going to change the firing pin. If the slide locks closed after each round than the firing pin is hitting the same every time. If I were you I would have looking into a new firing pin spring first, or taken more caution in reloading.

The only think a thicker stronger spring would do for you is last longer under more wear and use. But I have 5 stock 10rd mags that I use 2-3 times a month. 1-2 of the uses is at the range, and 1 use is at a USPSA/IPSC match. I have all my mags marked and so use mags 1 and 2 more because they are the ones that sit fully loaded in my nightstand safe. At the USPSA match I got through all 5 mags 6 times during the day, all mags are fully loaded after each round. I have been doing this for about a year now. I have had no problems, I also only shoot WWB and haven't gotten my reloading gear yet.

I'm glad your problem has gone away, but your reasoning behind the fix isn't logical.

If you are getting fliers, you need to re-consider your choice of bullet and powder (assuming these are reloads) and not be concerned about springs.

I have spent a lot more than six bucks on gun stuff that delivered far less. I can't even get a decent cigar anymore for six bucks. Cheers.

Can you get a good woman for six bucks anymore?

I think the stronger springs are holding the tip of the bullet up at a proper angle so it goes into the feed ramp at a better angle. This will make sure the slide does not "drag" as it is going into battery. If the slide slows down as it is going into battery, it might not finish fully into position. This could cause light strikes on the primer.

I also think the stronger springs help the bullets feed properly and keep then from nose diving causing a FTFeed.

At any rate, I spent about $30 on four new stronger springs and I havent looked back. All my ills have been cured. So if the reasoning doesnt compute for any of you then I suggest you keep your original mag springs.

If it is fixing FTF's for you that is understandable. But the questionable fix is the light primer strikes.

Dris, maybe i should rephrase and repost. i'll break it down:

these are the things that are going on with my XD:

1) a fully loaded mag (13 rd and AGP +3 extension) is sometimes EXTREMELY difficult to seat or impossible even after some really hard slams

2) a fully loaded mag is sometimes EXTREMELY difficult to release; i have to use A LOT of force with both hands to push the mag release button down

3) after a shot the mag would pop out (a huge PITA during combat training, let me tell 'ya)


So! my last comment was based on my belief that the AGP spring's higher tension may be causing these issues. You are correct: FTF is an unrelated issue and i should strike that from my post. But since you have had no problems with your AGP springs i have to ask: did you have ANY issues at all breaking them in? With my AGP extension (+3) it is IMPOSSIBLE to seat the mag with 16 rds in there-----too tight up top.

so basically if im not having light primer strikes than i don't need the AGP springs? also, is EVERYONE using stock springs having light primer strikes?

My XD-45 is only about three weeks old and the dealer had to order it to get the right finish, etc.. It has such stiff mag springs I doubt either 10 or 13-round mag could be fully loaded without a mag loader(uplula.)
The slide spring is stronger than I am and it's very difficult to pull the slide back without my hand slipping.
The throat is very nicely polished.
Some of these things may be only on the new XD but mine doesn't seem to need after-market springs or anything else. Maybe some of you with weak springs should contact the factory. They may have changed what they install.
My new one was perfect...literally on its first hundred rounds. I'm only waiting for my new reloading equipment(newbie) before shooting more so can't make long-term claims. Just guessing the company may have changed things recently.
