ok i had a question. i purchased the xd45 4inch barrel and not until afterwards i did my research and asked around and found out the only the v10 9mm and 40mm come ported at the barrel and slide. i called springfield today and they said they could port my 45 the same way for about 520.00. i was wondering if anyone knew another shop or place i could possibly get it ported? oh and if there's a reason why they didn't make the 45 in that option? unsafe? i tried researching and i didn't find a reason why it was bad. thanks in advance guys.
