based on what I have read in the rules using these items in a glock 34 for uspsa production is alright, but I just want to double check before I go through with it incase i have interpreted something wrong.
production trigger kit: http://www.uspsa.org/uspsa-store-product-details.php?Production-Trigger-Kit-from-Glocktriggers.com-108
(it says everywhere that it is approved, however I have to ask is this the lightest trigger available that I could use? I see 2.5lb triggers but they seem geared torwards limited and open)
magazine releases are a no go from what I have read, and lastly can any recommend a good quality steel guide rod and spring, i can't seem to find much on them.
I know much of this would be deemed as unnecissary modification but i got the money to waste, and wanna build a cool gun for competition. thanks for the help

Your best bet is to get a ruling from the USPSA itself. I feel certain you are correct in your assumptions, but I for one would hate to drive some distance only to find my gun disqualified.

All that stuff is legal.
Sights are always legal as long as they're notch/post type. Replacement barrels are legal if same length and chambering as original.
Trigger kits are legal as long as the visible part (trigger itself) is a factory part, which the version you linked to uses.
You can only use factory extended mag releases, but the Glock 34 already comes with one (many people including myself swap a 34 release into other models like the 17 though).
Wolff sells kits that include a non-captured rod and spring that will work great.
Look towards the bottom for "RECOIL GUIDE ROD & SPRING COMBINATION". I'd recommend going with the 14lbs version.
If I might critique though - the notch on the rear sight you specc'd is 0.115" with a .100" front blade. That's an incredibly narrow sight picture. Not bad for pinpoint accuracy, but IMHO it'll slow you down on sight aquisition quite a bit. With that narrow of a front blade I'd look more at something with at least a 0.135" notch. Personally my best balance that I like is the Sevigny style sights by Warren which are 0.115" front and 0.150" rear.

I'll second that.
A .110" wide Dawson front sight and a .150" wide rear Warren Sevigny Comp plain black rear is the way to go. That's perfect for G23/17/19/22. Some times a slightly wider .115" front is prefered as the G34/35's are longer.

great info on the sights, so you use fixed sights instead of adjustable? I just picked the adjustable on assumption alone. if fixed are indeed better based on your expeirience please if you could link a set you would recommend over them please do post it. as for guide rods, any thoughts on steel vs tungsten?
March 30, 2012, 09:29 PM
Tungsten guide rods are better as weight = good, but remember that there's a weight limit. You cannot exceed 2oz heavier than the published weight of a gun.
A Glock 34 is listed with an official weight of 26oz (that's with an empty mag inserted). Glocks are at a slight disadvantage here vs other guns as their stock sights and guide rod are polymer. Most other guns (even polymer framed ones) use steel sights and guide rods meaning the weight of steel is already built into the stock weight, giving you a little more wiggle room.
My advice: steel guide rods are relatively cheap. Tungsten ain't. Buy steel at first, get your gun setup, then weigh it with a mag. If you have enough buffer left over, get a tungsten. If not, stick with steel.
Also, your weight room will be particularly less if you do indeed go with adjustable sights as they weight a bit more.
Now, as to the sights question: it's not really that fixed sights are inherently better. The dilemma is: adjustable sights are often designed for guns that are being shot for peak accuracy. USPSA is about balancing speed with accuracy. You want to shoot fast and be accurate enough to keep your hits in the A-zone, but you're not really shooting for groups. With that in mind, many adjustable sets will have narrow pictures. If your goal was to take slow aim and shoot a quarter, then that's good. However, what you're wanting to do is usually take a faster shot and just be in an area about the size of a piece of notebook paper. Wider notches founds on fixed sights are often better for that as you can more quickly find the front sight.
My primary gun is a S&W M&P 9L and I use a Glock 17 as my backup gun. On my M&P, I run a combination: a Warren Sevigny Competition Rear (0.150" notch) and a Dawson Precision (0.115" wide x 0.180" tall) front sight.
On the Glock, I run a Warren Sevigny Carry set which runs the same dimensions as the above pair (the sight picture is virtually identical between the two).
I actually run a plain black front as I prefer that, but most shooters seem to go with a fiber-optic front so I'm linking in that version:
