Digby, Thanks for posting these pics! Very helpful!!! What's the width of the rear notches?

What did you get? What was the width of the front sight and of the rear notch? I just ordered adjustable black Dawson Precisions with a .100" front width and a .125" rear notch, though I'm tempted to get a .125/.150 combo instead.

I see your point. However, arguably, someone who shoots multiple guns might be better able to truly discern and notice something wrong/different with a particular gun vs someone who only uses that one gun, as having experience with a variety of things helps you have a proper baseline to detect material deviations. Sort of like Person A who has driven only one Toyota Camry his whole life vs Person B who has driven 50 Camrys and 50 other cars: I'm pretty sure that Person B can better appreciate the strengths and weaknesses of Camrys in general and, more importantly, discern whether any issues with Person A's specific Camry.

Interesting. I would think that the dual-spring would have more of a dip/flex, as it's a stronger spring and since the additional spring adds another variable. Check out this thread, for example: http://www.brianenos.com/forums/index.php?showtopic=138964&view=findpost&p=1563400 So, I was expecting the weaker spring to have a stronger kick back, but a gentler reset. However, you seemed to have experienced the opposite.

Did changing springs fix the problem?

The stock Glock spring is more than 12#, so it will wear out longer. But even stock Glock springs are supposed to be replaced every 3-4K rounds.

That's normal for almost every recoil spring.

Thanks for all the feedback, guys. I think I'll definitely go the L-10 route then.

Hi guys, As I’m new to USPSA, I wanted to get your thoughts as to whether I’m making the right choice in shooting in Limited-10. I’ve been shooting IDPA since July and had a blast shooting my first USPSA match last month using my IDPA gear (a stock Glock 35 .40 S&W with a lighter trigger and adjustable night sights). While I shot that match in Limited, I’m planning on shooting Major ammo in Limited-10 going forward (vs Limited or Production) for two reasons: 1) The additional points from shooting Major generally outweigh the benefits of shooting softer-shooting ammo, so might as well shoot Major ammo in Limited or L-10 2) Between Limited and L-10, the only difference is that Limited-10 has a 10-round limit on magazines and more folks shoot L-10 than Limited/Production (at least that seems the case here in NJ), so shooting in L-10 presents you with more people to baseline your performance with and see if you’re improving Does this make sense? Or am I better off shooting in Limited or Production? Thanks!

I'm assuming you don't have a Gen4 G34?

I actually lost a screw since it popped out while I was shooting, so I asked Billy at Jager for a spare. Now, I just rack the slide and remove the screw before shooting just to be sure. I don't suggest using loctite since you want to replace the spring anyway every few thousand rounds, and that'll be a lot harder to do if you use loctite.

Of course, if you're a Master level IDPA shooter, then maybe the few extra grams from a steel guide rod mean a material difference.

Yep, that's what I thought too until I racked the slide and saw the polymer part. I have both, both from Jager, and I personally don't see a measurable difference in my shooting. If the steel made a .1 second difference in my splits, I'd be all over it, but nope. At the end of the day, we're talking a few grams here, so I personally wouldn't move up to ESP just for that. But if you're looking to enjoy the other benefits of an ESP gun and will move to ESP regardless, then the extra few grams from the steel won't hurt.

Clarification: all the statements I made are limited to the context of Glocks in SSP.

Maybe I'm missing something, but isn't the IDPA Rulebook clear on how non-factory-material guide rods aren't allowed for SSP? Under the Excluded Modifications section of the Rulebook, it prohibits "4. Guide rods made of a material different from the factory part it replaces." Not sure what the discussion in the IDPA forum was, but based on this rule, any guide rod not made of polymer is clearly not SSP kosher.

The RSA in the Gen4 G35 is polymer. Pull back the slide and you can see it.

I haven't tried this, but I did have the same problem as you and switching to the non-extended lever fixed my problems, as well as making the slightest bit of change in my grip. Just looking at the pic of this product, I think this forward lever will only exacerbate the problem, as you'll have more metal to push down.

Lol. You'd think they'd charge less for selling a smaller version. Oh well. Cheers

Thanks. I bought IDPA paper targets from Target Barn and have bee quite happy with them: https://www.targetbarn.com/newstore2.asp?CAT=TARGETS&SubCat=PAPERTARGETS Even with shipping, they seem come out to around half the cost of the gunfun option.

17 pounds.

I am. I'm a girlie old man, and my elbows/joints don't hurt as much after I shoot if I stick with soft loads.

I've been screwing around with 3.6 loads that get me to 130-135 PF, using 180 gr flat-point straight shoulder Berrys at 1.125 OAL. I was getting a stovepipe every 100 rounds or so, so I dropped to an 11 pound recoil spring, and that fixed the problem. I got the polymer guide rods and the 11 and 13 pound springs from Jager.

I'm assuming you're purposefully trying to load ammo that shoots soft / that attains a low power factor. The base PF in IDPA is 125, and your loads are hitting 137-143 PF (similar to mine), so you just need to change the recoil spring if you want to shoot loads these soft. If you don't want to change recoil springs and/or don't mind shooting stronger ammo, then load up to 4.1, and you won't have stovepipe jams anymore.

No worries. Bullet grain * velocity (fps) / 1,000 = power factor. Basically, you need a lighter recoil spring, as the charge isn't strong enough cycle the slide fully to get rid of the spent brass. Get a 13 pound recoil spring to replace the stock recoil spring, and that should fix your problems.

Okay. Your power factor is over the 135 PF base that most Glocks run well in, and your load specs look normal. What malfunctions are you experiencing? I'm guessing you might be getting stovepipe jams, from the stock recoil spring being too strong for your minor loads.
