I have no idea why 5.7 has stuck around since stargate ended.

I dont really get the Five-Seven pistol, but out of the P90 I think the cartridge makes more sense. |

Are there any major improvements with the MK2? I'm looking to get one and there is about $100-$200 difference in price locally between the 2. Answering your question (and ignoring the trolling) The slide is a one piece milled piece on the MKII vs a two piece welded stamping, supposedly there are SOME beefed up parts in the frame. MOST USG holsters won't fit the MKII It really comes down to which one you think looks better. |

Buy a PMR30 and get the same ballistics for less money 40 gr 22 WMR at 1250 FPS is exactly the same as 40 gr 5.7 moving at 2000 FPS. 
ETA: Mk2 is the Mk2 for a reason. Improvements are minor, but they are noteworthy. Only irritation is getting fixed night sights.

Did I make it before the hurr-durr .22 magnum crowd? If not they'll likely be along shortly. The Mk2 has a one piece slide and adjustable sights. The POI between the different rounds can vary a good bit, so it's pretty nice to have the sights. Other than that a downside of the Mk2 is they generally need their own holsters unless they're a looser fitting variety.

Not to mention all black controls vs. grey and front slide serrations.

Isn't reloading the 5.7x28mm cartridge incredibly difficult? I remember reading that a few years ago when I had a Five-Seven boner and the reloading intricacies turned me off. Quote HistoryQuoted:

Shot one and loved it.
If it was cheaper I would own one. |

My wife still wants an SBR'd PS90.
But she bought the entire run of both SG-1 and Atlantis on DVD, soooo... |

If you load sensible loads you MIGHT get 5-7 loadings per casing. You should weigh EVERY charge. Keep in mind 50,000 c.u.p. in a TINY casing. The brass needs trimming every time. The cartridge doesn't show pressure spikes like most rounds, to determine if a load is too hot the best way is to section a casing and see if there is a bright ring close to the shoulder where a brass separation is beginning. Use a powder that has a nice gentle pressure curve when loading 5.7x28. True Blue is recommended by many. Some powders pressure spike with only a difference of .2 of a grain. You "wash" the brass with a solution of Simple Green and water. You shouldn't reload this cartridge with the intention of trying to come close to loads offered by Elite Ammunition. I carry Elite S4M (2,400 fps+) but that's not something a home loader should even begin to try and copy. |

Not much difference between loading the 5.7 and other cartridges, BUT, it's not a round to attempt to "hot rod". If you load sensible loads you MIGHT get 5-7 loadings per casing.

Any reason S4 over T6B? Buffman RANGE who tests all the 5.7 stuff seemed to like T6B a bit more. I've been considering changing to the T6B (I have some). There is no doubt that it offers better penetration. |
