on my PT 1911 it came factory with Ambidextrous thumb safety's. I want to change grips and because of this fact it is making this simple task hard. so my question is can I eliminate the right hand side thumb safety or will something like this( http://www.midwayusa.com/eproductpage.exe/showproduct?saleitemid=773870&t=11082005 ) that i found on midway USA solve my problem?
