    Lightweight Steel Striker

    in Glock

    Posted

    Apparently a popular skeletonized striker weighs 6 grams. Based on my home striker lightening mine weighs approx. 6.7 grams (I don't own a digital scale). I'm satisfied. No offense intended toward the manufacturers of lightened strikers. I'm just broke these days and need to do it myself.

    Seems to me it's the same idea as taking mass off of the hammer on a revolver. The springs can push it easier. And it gets going sooner and so whacks the primer harder.

    I took 11 grains off of my stock striker after a bad match where I couldn't get through a single mag. I took that spring (Reduced Power) back to the range using the lightened striker and it works again. For how long I don't know. But presumably a new RP striker spring will work and be reliable much longer. I now keep a log of how many rounds down range for each spring set up.

    I'm sure there is a point of diminishing return regarding how much to lighten a spring. But a lightened striker and a RP striker spring seems to me to be a good marriage. I wonder how much a skeletonized steel striker weighs.

    Building the ideal limited glock?

    in Glock

    Posted

    Thanks Flex you are the second person to tell me that. But does that mean LWD would have to sell 500 G20 tactical length complete slides with .40 barrels...or entire guns configured that way?

    Today I ran some 10mm, 200gn loads making major through a stock G20 and it was very soft indeed. And the whole setup very light. I don't do well with a heavy gun. I have a very nice SV sight tracker set up now and I am struggling. Jish. :surprise:

    And what about shooting .40cal through 10mm mags? No biggie?

    Thanks again,

    Rick

    I was thinking of getting a G20. Putting a LWD G20 tactical length complete slide with a .40 cal barrel on it and running it in limited. Would that be better still? And does the .40 cartridge run ok in the 10mm magazine?

    38 caliber (.357) bullets out of a 9mm?

    in 9mm/38 Caliber

    Posted

    Very pleased to see this post as I have about 6k MG 142gn .357. Been shooting them over 3.1 of Tightgroup @ 1.100. Pretty darn accurate. Been wondering...I also have about 5k 200gn .358 that I shot out of my 686 in IDPA last year. The 142 are jacketed. These (200gn) are lead.

    .358 is too big right?

    200gn is too heavy, right?

    Does anyone make a 9mm bullet that heavy?

    What do you guys think?

    Thanks so much,

    Pistol gripping issues

    in Handgun Techniques

    Posted

    This a very helpful thread. I have a question.

    If I am using the correct thumbs forward grip with good weak hand grip panel contact. And my weak (support) hand is tight up under the trigger guard. Is my support pinky finger (at it's base) making hard contact with the bottom of the handgun grip forcing the camming action?

    Seems like it's there but not pressing, just making contact.

    I hope my question makes sense.

    Thanks,

    Rick

    Seeing Double With Both Eyes Open

    in Tips for Improvement

    Posted

    This thread is stunning to me. Last night for the first time I experienced some double vision while shooting a steel match. I shot the rest of the match with my left I closed. Now my left eye is a "lazy eye". Some of you in your forties may be familiar with the "lazy eye" or Ambliopia. Not sure about the spelling. My right eye is dominant and has perfect vision. The left is the lazy eye and quite fuzzy. I wore glasses to strengthen my lazy eye and a patch over my good eye when I was a kid for years.

    I will try the tape deal over my left eye though it must be opaque. It's already fuzzy and the double vision shows me a clear image and a fuzzy one. Very distracting indeed. It made my head swim.

    I feel so much better after reading your postings. Last night was very disconcerting, I thought it was just me and my lazy eye.

    Thanks so much.

    Dedicated SS'er?

    in USPSA/IPSC Shooting

    Posted

    I've neglected my SS. It's my nicest gun. A Valtro. Mostly been a Revo guy. I'll shoot the WSSSC and jump to Limited (new gun) I'm buying a SV set up as a Sight Tracker. I'll save my SS for the monthly IDPA match. I guess I just like major. I'm new to USPSA. Solid for a little more than a month now. I love it. I came from IDPA. USPSA, more shooting, more fun. :roflol:

    I like this forum too. :cheers:

    Hollow base .45acp

    in 44/45 Caliber

    Posted

    I ended up going to 4.8 Clays. For the Hollow base OAL is 1.200, for the Midstates OAL is 1.25. The hollow base over 4.6gns Clays doesn't cut it.

    All show very, very slight signs of pressure. I would like to use the Moly coated hollow base as my primary load 'cause I think they will chamber more reliably. The Midstates have a shoulder.

    Thanks again Carlos,

    Hollow base .45acp

    in 44/45 Caliber

    No need to abandon Clays since .45 ACP runs such incredibly LOW, safe pressures plus you are only going for Major + slight margin.

    You are right that the hollow base effectively increases case capacity - all else being equal. You are also right about having to use a little more powder to get to the same PF.

    I used to shoot only Clays over 185s and 200s from a STI Edge .45 ACP. Never had any problem with low-pressure .45 ACP, and in fact, Clays is designed around low pressure shotgun clay-bird reloading. Your .45 will only generate about 15,000 to 17,000 PSI. Your gun can actually handle a lot more pressure than that (google .45 Super). The danger with Clays in our sport comes in .40 cal where the industry pressure is supposed to be 35,000 PSI or more. Much of that danger went away when the power factor was lowered and most folks began loading VERY long for the STI guns (plus the 200s fell out of favor). As you can see, there is a very WIDE safety margin for loading Clays in .45 ACP with your coated 200 grain 45 ACP bullets.

    I just bought some 200gr Hollowbase .45acp bullets. Bear Creek as a matter of fact. Does the fact that the bullets have that hollow base change the load data? It must, decreasing pressure. Causing you to have to add powder. I thought I was making major with 4.6 grns of clays under a 200grn. midstates lead bullet. The same load date with the hollow base bullets yeilded much lower velocities. Tomorrow I will double check the velocities on my current load (midstates, no hollow base) to make sure. But does that sound right? If so it seems I should switch powders as Clays is to fast burning to fast simply keep adding and adding.What do you think?

    Where do I go from here?

    Rick

    Thank you Carlos. Very reassuring. I will work it up carefully.
