I got the following in an email from SIG's marketing email blast earlier in the week. It's still not cheap, but it isn't a bad price for the conversion. I ordered one for myself; I'll let you know how it does. It's not in the email, but they are also discounting the mags. Apparently full list is an outrageous $45, but they're doing $35 for one or $30/ea for two or more. That's pretty cheap considering CDNN still wants $33 for them . . . man that's a lot of money for a plastic mag.
