I own an MP pt145 also...It's great
With the 40 having an 35kpsi max pressure and the 45 having a 22kpsi max pressure, I'd have to argue for the 40 as far as speed out of the shorter barrels. But 45 acp is one of the easiest ammos to get nearly anywhere, I see the 40 alot, but it's routinely understocked in my shopping grounds of BiMart and GI Joes in the PNW region.
I really like my Pt145, so much so that I bought my wife a PT111 for less recoil. She did not like the 45 much, and with the higher pressure specs, I suppose the 40 kicks even more, maybe 1.5 times as much from some crude comparison calculations I did using the max pressure spec and inner diameter of the cartridge as the intantaneous force going back into the slide, the 40 beat the 45 by a large margin.
I've run the speer 230 ashtrays through it without issue. Matter of fact, I've run 3 flavors of handloads (Hornady 185/230/speer 230) and 3 flavors of factory ammo (ump ball/win185silvertips/federal 230 Hydrashocks) through it with no issues either. About 600 rounds through the barrel now without any ammo or gun related problems. I squeezed the mag release while plinking and it partially dropped the mag and did not chamber the next round properly, my fault, not the gun or the ammo. The feedramps on these models is particularly well polished.
I'm wish someone would offer the smaller 147 grain bullets I see that come out of mexico, can't recall the name just now. They should be able to offer some serious velocity out that short barrel, espeicially since the 230 grainers don't move all that fast in comparison to longer barrel guns.
I took some fine grit paper (1200) to the slide's inner rails and just spent about 5 minutes knocking off the high spots. The slide is much smoother now and I consider this fairly important because the mating rail is anodized aluminum, not steel. Plus it just feels better when cycling it manually, I like that smoothness, especially for the 5 minutes extra work it took while cleaning it. If you do this, less is more.
I am finding the same response from folks about Taurus, that's a cheapie, how could you do that routine. Then I go shoot it with them, all arguments cease after that.
I think Taurus makes good products, I bought another and would consider anything in their current product line worthy and a sound financial investment. I'll share my thoughts on my wife's pt111 when we get around to plinkin it this week or next. It's the stainless model, looks nice.
