The slide is thinner. Glocks stats for pistol thickness measure at its widest point which is somewhere on the lower...perhaps across the lower at the mag release? (null)

AFAIK, the 41 slide is as slim as the 30S/36 slide. The difference in slide mass is quite noticeable when holding a 30SF vs a 30S. Even though the 41 slide is almost an inch longer than the 21, the upper is 2.3oz lighter than a 21's. That's not quite as big a difference as the 30SF/30S, but I bet it's still noticeable.

Not sure what you mean. The upgrade fee on a pistol award cert for a Gen4 34,35,41 is $142, which is kind of steep IMO...but what's that got to do with membership renewal? If you could find a blue label one at a willing dealer, the 41 and 42 make more sense to buy at discount than on a prize certificate...but they're kind of tough to find right now. That's why I used a pair of certs I had to order them directly from Glock.

That's just crazy talk. I've got a 21SF, 30SF, 30S, and a 41 on order. To me, the 30S has made the 30SF redundant. The 30S and 41 were/are prize guns (30S won shooting the 21SF, 41 won shooting the 30S)...so I didn't have to pay much for them. Agreed.

I briefly owned a Gen4 17 that would pattern more than group. I'd been shooting Glocks for about 10 years and was fine with my old Gen3 17. I couldn't figure out what the problem was and dumped it at a loss in frustration. I wonder now if it was a loose locking block? (null)

Easier said than done. I HATE the new interface to their online load data...and surprise, surprise, the PoS new web site has fallen over and is completely unusable now. Additional uncaught exception thrown while handling exception.

Bullseye may be kind of fast for 147gr 9mm. For WSF, I'd start at the bottom (Hodgdon says 3.9-4.3gr) and only work up from there if you don't get the velocity you want. I've never used WSF, but with Universal, I find that with 124gr bullets, starting loads work fine, but for 147gr loads, I had to go to max loads to get consistent/complete combustion and the velocity I wanted.

I don't think burn rate makes a huge difference for 147gr 9mm. With a variety of 147gr bullets, I've used WST (on the faster end) and Universal (more of a medium burner) and don't notice the difference. I prefer WST with the coating Precision uses (due to smoke/smell), but with Hi-Tek coated, plated, or jacketed, either one is fine, and I use Universal because I have more of it and hate it in .45, where WST is my preferred powder.

My order from Black and Blue actually included a few free samples, one of which was 135gr .356. I tried one load with these, 4.0gr Universal Clays @ 1.135" and maybe it's not a fair comparison, but I thought they were much snappier than the 147s. They averaged 1019fps though, which puts them a bit higher PF (137 vs 133). There's really no comparison between the old moly/dry lube/whatever it actually is coatings BBI used to use and Precision still uses and the Hi-Tek coating Bayou made popular in the US. I wish someone made a 200gr .45 bullet the shape Precision makes, but in the Hi-Tek coating.

I'll have to shoot some more of each to be sure...last outing was really just to chronograph all the loads. Assuming no accuracy or fouling/leading issues show up with either, I think they could be used interchangeably. Black and Blue is slightly cheaper and easier to order. I may try the 105gr .38's with around 3gr of regular Clays and see what that does.

I would think using one of the Sharpie methods or some kind of dye similar to Sharpie would be far safer to apply.

The 105s were tricky because I couldn't find any data for them with powders I have/wanted to use. Previously, all my .38spl has been done with WST (which is my preferred powder for lead). I figured, these being coated, I could give Universal Clays a try. I did 18 each at 4.8gr Universal (761fps) and 5gr Universal (781fps). 4.8 left lots of unburned powder. 5 left only a little. I plan to try these again with WST...probably 3.8-4gr based on what I've done with 125gr bullets. The 147s shot indistinguishably from Bayou. Each did 900fps with 3.4gr Universal at 1.130-1.135" OAL. The real surprise was the 180gr .45s. I was expecting feeding issues, but there were none. They all fired just fine, but it's still not a load I plan to do any more of. I'll leave the .45275 bullets for LC shooters. With 4.8gr WST, I got 837fps from a Glock 21, and 778fps from a G30S.

I just loaded some more B&B bullets, this time 105gr .38spl...and this is a first for me. I found 2 "wrong bullets" in the box of bullets as I was counting out a small number from the box to the bullet tray to load my samples. Luckily, these were obvious (147gr 9mm vs 105gr .38). I've dealt with PD, MG, Zero, Xtreme, and never had (that I've noticed) wrong bullets in a box. I guess it must happen from time to time? Seems like it could really foul things up if not caught.

Either would work. Since AC is conveniently located, and beats having to replace batteries, I use an old 120VAC to 9VDC 1A transformer left over from some forgotten electronic device. 9V 1A is way overkill for the 9 LEDs I'm running, but it's what I had freely available.

I just loaded a few of these 180gr .45 bullets, and I'm calling them a failure even before getting to the range. They had to be loaded real short (<=1.165") to not jam up into the rifling. They don't like to seat squarely no matter how careful/deliberate I am with the placement. Because of this, most have a side bulge at the bullet base and don't come close to gauging. This is one of the few bullets they don't offer a range of sizings of...and they're fat. I mic'd them at .45275. The Precision coated bullets I load in .45 are sold as .451 and mic just a fraction over that. I'll test fire and chronograph these "just for the record", but I think the rest of the box is going to go to the next range swap meet and hopefully end up with someone who loads .45LC. It's disappointing, because there was a review on their site from someone saying he'd loaded them for a light load in an M&P .45acp. I've got more hope for the 147s. They mic identically to the Bayous that I have and I didn't have any trouble loading them.

I can do he leg work of finding the stuff but you happen to have a parts list of what you needed. I'd rather do it myself building things is more intriguing than paying someone to build it for me Sent from my iPad using Tapatalk HD Here's the LED roll I bought: http://www.amazon.com/gp/product/B004ZUYI72/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1 The adhesive issue, I solved by using some common foam double faced tape. Only warning there is that due to the added thickness, be careful with the ceiling strip positioning so that there's no LED where the shell plate fingers are when you raise the ram. The other small parts needed were: an old transformer I had lying around. I decided 12V was too bright/harsh and used a 9VDC one wire...I actually used some scrap ethernet I bought a rotary switch and some tiny M/F plug connectors to make it possible to disconnect power from each LED strip at a local "electronics junk store" Then it was just a matter of doing a bit of soldering and application of some heat shrink tubing. Oh...and this roll of LED has a clear rubber-like protective coating. It's easily peeled off...and for the ceiling one, I did that. I think that's why someone mentioned filing the shell plate fingers. Just make the LED strip lower profile instead.

So, which directions did you really mean?

The B&B 147s run 0.010" shorter than the Bayou 147s. With no adjustment to the press, they come out 0.005" shorter than the Bayou 147s...so the bullet nose profile must be slightly different as well. I loaded 50 to try out. I'm going to try loading some 180gr .45acp next and see if they'll feed.

True...but you should also run some of that through it to verify reliable function...and I'm not aware of any commonly available factory loaded SWC. I guess you were hoping to break it in with SWC before switching to the good stuff. Glocks don't generally need much in the way of break-in.

Seriously? What's this factory ammo you speak of? Oh, that stuff they sell at Walmart for $20 or so a box? I stopped buying factory pistol ammo >6 years ago. I suspect anything they have would work. Preferably not steel cased though.

Moving the rear sight to the right would compensate/correct for a gun that hits to the left of POA.

You're going to need some kind of rounder nose bullet for the 30SF. 230gr FMJ should be fine. I've used PD and Zero. Most 230gr JHP should work. I've used Zero. 200gr RNFP from Precision work fine. 185gr JHP from PD and Zero can work, but particularly with the Zeros there's narrow OAL sweet spot. Too long, and they won't chamber. Too short, the 30SF won't reliably feed from G21 mags. I rarely use the smaller G30 mags, so I don't know if its an issue with them. AFAIK, any bullet with an exposed shoulder is not likely to feed reliably in a 30SF.

I wanted to try something new, and B&B offers a light .45 bullet in a profile I've not seen anyone else offering. It's meant for .45LC, but I'm going to try loading it in .45acp and hope it feeds in Glocks. It didn't hurt that in small quantities, B&B is slightly cheaper than the other options.

I got my first order from Black and Blue. I'm a little disappointed already. From the pictures, I thought they were using the same 147gr mold as Bayou, but the bullets are not the same. B&B's are slightly shorter (I didn't write down the measurements) and have quite a bit less bevel at the bottom. They also don't feel quite as slick as the Bayou bullets and the color of the Hi-Tek coating appears to be a little less consistent. It's a little hard to judge the color issue since I ordered a lighter color than the dark green Bayou bullets I have. On the plus side, they threw in a couple of sample packs of bullet weights I didn't order in calibers I did. The real tests will be how they load and how they shoot, so I'll try getting some loaded in the next night or two and hopefully get to the range this weekend.

Probably nothing. My experience with them and problem guns has been that they will fix them, but generally won't say what "the fix" was. Twice, I've sent in pistols that were not functioning reliably/properly (with factory ammo), and both times they came back problem solved, no explanation. It's interesting that the POI issue was apparently caused by a loose locking block. I would have thought if the locking block was loose in the frame, POI would be erratic rather than consistently off. 4" at 20yds would be about 20MOA, no?
