Lugnut,
SP02309 G17/G34 9mm 10 round mags only
SP02323 G22/G35 .40 10 round mags (I've seen this listed for G17/G34 10 rounders too)
Here's what I have for "SP02323"
SP02323 Magazine Spring-G20-G22 10-rd mags only
SP00448 G17/G34 9mm Hi cap mags (I've seen this listed for G22/G35 hi caps as well)
Don't have this one listed for G22/G35.
G22- SP 02323 10rnd mags only
G35- SP 02551
SP02551 G22/G35 .40 hi cap mags- 11 coils for .40 hi caps also G31 and G37
Is this what you guys have found? Should I use the SP02323 for my G34 as well? No go with SP 02309. Is the SP00448 too weak for the .40 hi cap mags? This is listed for 15rnd mags so it should be "extra" power for 10rnd mags if I understand the question correctly. Or am I making too much of this mess? I don't feel like having ANY issues at matches and I need to replace these springs. Glock direct really didn't help clear any of this up either. That's how they've rolled for a long time
Brownells sells a tool for taking floor plates off.... it's ok. I think the "GTUL" is the way to go (from looks, I don't have one yet). It's not a big deal to do, you probably don't need to do it, but I say go for it. Hope this helps.
