Hmmm, I think it was the "full" size 10 lb spring that I ordered. I'll try that.

In case anyone is looking and you have a BJ's wholesale club nearby, mine had the ION AirPro II for $90 the other day. It does WIFI for use with a phone app.

It happened Friday night several times, during the classifier...annoying. Now, I have polished almost everything up (I still want to polish the firing pin safety plunger) and the slide seems to be moving better. I also did a little bit of work on the roll pin to allow the extractor to move more freely (it was very, very stiff). ...then I had problems with rounds tilting up out of the magazine...so I have now bent the magazine feed lips in a little. It now works pretty dependably at home by hand. We'll see at the range.... I guess it's a repetitive process...find a problem, fix it, expose another one, fix it...etc.

I wish I had taken pictures. As the slide is moving forward, the hammer is still in contact with the center of the slide (which reset it as it was going back). When the back end of the slide re-approaches the hammer, the hammer jumps up until it hits the firing pin retainer, then slides off the retainer into its final position as the slide assembly clears the hammer (the retainer is the last part of the assembly in contact with the hammer). The retainer has the same profile as the bottom of the slide and looks like it should provide a smooth transition of the hammer. It doesn't because the bottom of the retainer and the bottom of the slide aren't coplanar. The retainer has some "slop" which allows the bottom of it to be higher than the bottom of the slide. I wish I had the pistol in front of me for a picture or two.... I know 1911's need to have their firing pin retainers polished sometimes. In my limited experience though, I haven't seen a firing pin retainer before that didn't extend to the bottom of the slide or a really loose one.

Update: I cleaned those up and polished them and the feed ramp (just in case). I noticed that, as the slide moves forward, the hammer hits the center back part of the slide and it feels like a pretty hard transition. Of course, I realize I'm doing it by hand and feeling for problems, so I might be making too much of it. The firing pin retainer, with it's smoother and rounded transition surface, just moves out of the way leaving that sharp slide back edge to move the hammer out of the way. The retainer is not tight to the retainer groove in the slide and feels like it has a lot of slop in it. It feels better when cycling by hand and with snap-caps in it. It may be good enough. I can't tell at this point. I won't get to shoot it until tonight. Are those firing pin retainers usually loose? If not, is there a standard way to tighten them up?

Nice!, thank you both. I'll try that!

I've recently been having some annoying problems with my limited pro in .40SW. I've been running with low power ammo, around 130 PF using 155 grain moly coated bullets and a 10lb slide spring. Lately, I've been having problems with the sliding returning very slowly (or not at all) to battery after a reload. Everything looks normal after a round is fired. Last night, I thought it was due to the slide release, but I recovered (during a stage) by slapping the back of the slide into battery...which means the slide release had been triggered. I thought it might be a little problem with the slide to frame fit, but pulled the barrel and there was no resistance whatever, that I could feel. I don't notice any problems during dry-fire reloads, but I do that in my nice warm house. My shooting, with this pistol, has all been done at 40 degrees F or below on our range I thought it might just be the cold and the type of lube I'm using (just commercial veggy-oil based RAND CRP), but I was told by an expert with these, that it wouldn't happen. The things I haven't ruled out yet are problems with the magazine, where resistance of a round being stripped off is causing it and/or the barrel to slide fit...or something I haven't thought of yet. I suspect it's not the magazine, because I haven't changed the springs yet, so the upward force hasn't suddenly increased. If I don't have a better way to go, my next step is to just really slather it in oil, especially around the rear of the barrel area. Any advice?

I don't know the pistol, but if it's like a lot of other OEM advertised measurements, they may be off a little. You need to measure one to find out. There may also be a slide release or something where you can easily reduce the size by the small amount it needs. Right before I bought my limited pro, folks swore that it wouldn't fit in the box...but it did. Measure one.

Just have her go to a gun store and put a bunch in her hands...better if she can test them out of course. I like the feel of the Walther PPQ and I believe the ergonomic depressions would be good for a small hand (with the small backstrap). We have a lot of women shooting different caliber versions at our ladies night events.

I'm sure this has been covered somewhere in here, but I can't seem to find it. I shoot a limited pro .40sw 155 gr bullet at about 130 PF. Right now, my pistol feels like it is sprung too tightly for minor. I'm seeing a lot of conflicting numbers in an internet search. If anyone is running .40 minor, what recoil spring are you using. Thanks

About one in 50 rounds, my limited pro doesn't set the primer off on the first strike. They usually go off if I try them later in another gun or even with this one. Is this the type of thing the extended firing pin could help with? Thanks

Are we all talking about the same flakes...about 1/8 inch to 1/4 inch flat carbon with random shaped edges and light enough to float down slowly? I've seen them randomly and with more powders than just Titegroup. For the longest time, I thought they were just coming out of our ventilation...lol

Don't know, but I just heard that the North Carolina Cup will not be an IDPA sanctioned event next year. It was also left out of the IDPA schedule so I don't think it's a rumor.

I believe you have to look at the bullet shape. For .40 sw, I can load some, say Xtremes, pretty long, say 1.135, where I have to drop Precisions to 1.085. It depends on the maximum thickness at the shoulder and how far that shoulder is from the front of the bullet. The first time I shot my limited pro in competition, I loaded the precisions like I had the Xtremes and only made it through one stage. I didn't do the plunk test and paid the price for it.

I've heard that peep sight works well for Bullseye, but because of the constantly changing angles with the targets in action shooting, it may not work so well. Before you spend a whole lot of money, try some full lens safety readers (no transition, all reader). I got some off Amazon for about $14. Another shooter pointed me at them and I always use them to shoot now because both of my sights are in perfect focus. I still have some problems with some cataracts in low light and no, it doesn't help astigmatism, but you might be able to tell if you want something like that before spending the big bucks with the doctor...Just a suggestion.

I have this on three forums and have actually been surprised, with all the detailed rules discussions that go on, how few responses it's gotten. I'm feeling better about it though. Even though I probably got it wrong, so would have a lot of other people. 4 people have said 1 PE for not following the course of fire. 5 people have said 2 PEs, 1 for each step not taken 3 people have said 3 PE's, 1 for each step not taken and 1 for not following the course of fire. 1 person said 7 1 person said 12. I would have called two but agree now that it should have been one. The actual call was that the person was given three. Since I started studying the rules and playing SO on occasion (non-sanctioned matches with a real one as the scorekeeper), I've really come to appreciate what they do and just how hard it is...and how stressful.

Hey, anybody know where I can get a shell stop hitch pin...quicker than waiting for Mossberg to send one? My forward shell stop pin broke again. I replaced it with a small cut off drill bit that fits. That little hitch pin, that holds the main shell stop assembly pin from falling out the bottom of the receiver, shot across the room somewhere. Home depot and Lowes don't sell anything that small. I'm thinking about just putting a drop of lock tite or glue to hold it in until I can get one. Anybody have any experience with doing that or another option?

You have a course of fire that calls for 2 shots at three targets strong-hand, a step back, then a reload 2 more shots at the same three targets weak hand, a step sideways, then another reload 2 more shots at the same three targets free hand. The gun and all magazines had to be loaded to six rounds so both reloads were "emergency". It was a standard stage and was limited. The competitor forgets to move and shoots them all from the same spot, doing the reloads as the course of fire demands. How many PE's does he or she get and why? I'm asking because I really don't know. My thought differed from the 3 SO's I talked to about it who changed their answers as they found out what the others thought...lol

Exactly. Since there seems to be no particular upside or reason for this change (that has been stated---did I miss something substantive?) and I'm not particularly in favor of "change for no reason but change!" the fact that this will seem to effectively punish that lower-third-group seems counterproductive for a sport that is supposedly for everyone. While I'll still support IDPA, if I can (besides, there are no alternatives around here anyway...lol), I agree wholeheartedly that the risk of losing members/clubs is too great to be making such a move without marketing the need for the change a little better than simply using some esoteric "founders intent" argument. I keep reading the argument that "it won't change things", to sell it. That's more of a reason not to do it than to do it. Change costs money and requires training. There is a large and now substantiated risk of playing with the rules for the sake of playing. I just heard yesterday that another range for another major IDPA match is disassociating itself with IDPA, I just hope the trend doesn't continue. I'm pretty sure though, that it is going to be lot harder to get people from our training matches to start going to our regular ones, once they see the scores spread out even more. The current scoring system and where they fit in it, is discouraging the new shooters now. They feel they just aren't ready for the regular matches. I just wish I could give them a good valid reason why it is happening...one that makes at least some sense.

I know USPSA requires that, but I thought that IDPA SSP guns started hammer back safety on? ESP allows hammer back safety on. DA/SA pistols can start either way in ESP. SSP doesn't allow SA, so I would have to start in DA, (with or without the safety though).

Just to follow up; the gun fit in the box pretty easily length and height-wise. Our club bought the box from IDPA and it was checked by one of our MD's. I just removed the strong hand side safety lever by simply removing the roll pin. The shaft sticks out a little further than I would like, but our local safety officer instructor (and Tanfo gunsmith, by the way) said it would be perfectly legal in ESP that way. I'm not ready or comfortable enough to drop the hammer during load and make ready yet anyway, to be able to use it in SSP. When I am, I might look into replacing it.

I went out a little nervously to our biweekly match with a new gun (and new caliber for me). I didn't have much experience with it yet, but had shot it a little and the recipe felt good. First stage, on second first magazine, it wouldn't go into battery. Couldn't clear it. Finally got the round out with help. Thinking it was just one bad round, I went to the second stage...surprise, one of the best stages I've ever shot. Third stage, three rounds, then wouldn't go into battery, had to clear, then a shot and another jam. Durn, found another bad one. Fourth stage, one shot, then same thing. Got home and noticed that while the overall length looked good, the bullets I was using had a different ogive, with the shoulders much further out. Hmmm, needed to be almost .050" shorter. I had matched the "standard length", but forgot that bullet shape matters...and didn't case gauge. Daaahhhhh!

Thanks for the help. Bought the bladetech from Ben Stoeger's pro shop...reasonable price and shipped within a few hours of the order. Fits well and works good.

This whole thing could be solved with a few 3 axis accelerometers, some recording/processing gear and a fixture to support the guns. From a business standpoint though, it would be risky. You would have to really have confidence that yours is better to fund such tests. The boundary conditions, the non-linear nature and application of the forces involved (like gas expansion into atmosphere or drag from the hammer spring), fit-up of the components, even the lubrication, make this a problem that is probably better left off paper and put into the laboratory. IMO, you need to make too many assumptions on potentially relevant issues to simplify it enough to make recoil perception into a simple classical dynamics problem.

why did it go click? Racked the slide during load and make ready, then holstered. Mag was fully seated. A round, maybe 8 down was stuck, so no spring pressure on follower. I started the stage empty. You lose a lot of time figuring out what is going on. Press check is cheap insurance for me and now acts as part of a starting "ritual", which helps my jitters.
