Juan, you will want practice ammo that is not too much weaker than what you plan to carry for self defense:https://www.budsgunshop.com/catalog/product_info.php/cPath/656_2081_10000572/products_id/5420/SIG%20E45AP1-50%2045%20200%20JHP%20VCROWN50/20/ https://www.budsgunshop.com/catalog/product_info.php/cPath/656_2081_10000572/products_id/96698/SIG%20E45BA3-50%2045%20230%20FMJ%20ELITE%2050/20/ and for actual self defense ammunition :

I practice with the federal 230 grain ball ammo from wally world or other low cost local retailer

I had a Taurus 1911 for a little while and it was reliable with pretty much everything, just wide mouth hollow points would tend to hang up.
